The Stretchable display : The evolution into the ultimate display
Over the past few years, information display has developed remarkably taking on various forms and new appearances. Among them, flexible display has received significant attention due to its applications such as curved, bendable, foldable, and rollable display. However, the currently developed flexible displays have limitations in implementing design-free, because they can only be deformed in specific positions or directions. For the realization of true design-free as the ultimate display, a stretchable display technology is needed that is not only resilient but also capable of stretching and transforming into various forms without easily breaking.
This presentation will discuss the principal approaches and technical challenges to realize a commercially viable stretchable display.

From Micrograms to Tonnes: Enabling the Large-Scale Deployment of Quantum Dots
The rapid advancement of display technology has always aimed to deliver immersive visual experiences to consumers.  Achieving this goal requires overcoming various challenges, including technical performance such as sufficiently high resolution, life-like color, realistic high-dynamic-range (HDR) and cost-effective manufacturing at the massive 250 million-square-meter-per-year scale of the display industry. Quantum Dot (QD) technology delivers the best, most immersive visual experiences with great value to consumers today, and, as a result, QD technology continues to gain momentum in the display market. In 2023, consumers will have over 400 QD-powered display products to choose from. These products include displays of all types, from 1” VR headsets to notebooks, monitors, and the largest 110” TVs on the market. In fact, over 50% of premium TVs sold this year will contain QD technologies, including QDEF-MiniLED TVs and QD-OLED TVs. However, over 80% of the TVs sold globally are priced below $500. Can QD technology deliver its proven, premium visual experience at the cost and scale necessary to penetrate this important segment of the display market? In this presentation, we will outline the transformative journey of QD manufacturing and present future advancements in QD manufacturing technology to support the growing demand in the display market.

Patternable Perovskite Nanocrystals for Color Conversion in Next Generation Displays
Perovskites have recently emerged as ideal materials for in-pixel colour conversion where blue light is converted into red and green at the pixel level, such as in QD-OLED or µLED displays. With their very high absorption properties they can achieve nearly complete blue light absorption with very thin layers, opening the way for colour filter free architectures. Moreover, their narrow emission band and symmetric peaks enable the generation of ultra-wide colour gamut displays. However, to develop products suitable for the display industry, two major challenges must be addressed: patternability and reliability. Ink-jet printing (IJP) has only recently achieved the maturity required for large scale production. However, the resolution is limited and will not be suitable for most µLED displays where 2000 ppi or more is desired. It is expected that both approaches–inkjet printing and photolithography– will be required to address the needs of the market. Therefore, we have been focusing on the development of perovskite colloidal dispersions suitable for formulations as IJP inks or photoresists. In this contribution, we present our recent achievements towards performant and reliable high resolution patterned perovskite colour conversion layers. We have developed high quality and stable green and red perovskite nanocrystals and demonstrate their use in high resolution acrylate-based photoresists and demonstrate ink-jet printing.

Session III: Sensors and other QD Applications
InAs quantum dots for SWIR sensors
InAs colloidal quantum dots (QDs) have become promising alternatives for lead- and mercury-free, solution-based semiconductors in short-wave infrared (SWIR) sensors. These quantum dots possess a suitable bandgap that can be adjusted by varying their particle size, and they exhibit favourable properties for transporting charge carriers. However, the difficulties encountered in the synthesis of InAs quantum dots have hindered the development of InAs QD SWIR sensors. Our presentation will showcase different types of InAs quantum dot materials and highlight their effectiveness in SWIR sensors within the 1100-1600 nm wavelength range.

Atomic Layer Deposition for High-Resolution and Brightness Colloidal Quantum Dot Display Applications
Colloidal quantum dot-based light-emitting diodes (QD-LEDs) are one of the future emissive displays and high-resolution patterning of quantum dot (QD) films is one of the preconditions for the practical use of QD-based emissive display. In this study, we introduce the ZnO interlayer by atomic layer deposition (ALD) to enhance the performance and lifetime of CdZnSeS/ZnS core/shell QD-LEDs. Recently, inkjet and transfer printing have been actively developed; however, high-resolution patterning is still limited owing to nozzle clogging issues and the coffee ring effect and kinetic parameters such as pick-up and peeling speed. Consequently, employing direct optical lithography would be highly beneficial owing to its well-established process in the semiconductor industry. However, exposing the photoresist (PR) on top of the QD film deteriorates the QD film underneath. This is because the majority of the solvents for PR easily dissolve the pre-existing QD films. We present a conventional optical lithography process to obtain solvent resistance by reacting the QD film surface with diethylzinc precursors. It was confirmed that, by simple surface crosslinking of the QD surface and coating of the PR, a typical photolithography process can be performed to generate a red/green/blue pixel of 3000 PPI or more. QD electroluminescence devices were fabricated with all primary colors of QDs; moreover, compared to reference QD-LED devices, the patterned QD-LED devices exhibited enhanced brightness and efficiency.

Developing Pervoskite Quantum Dots for Display Technology
Perovskite quantum dots (PQDs) are now emerging as functional materials for many photonic applications due to their superior optical properties and easy fabrication. In 2105, we reported the room temperature ligand assisted reprecipitation synthesis (LARP) for brightly luminescence perovskite quantum dots. In 2016, we demonstrated the in-situ fabrication of hybrid perovskite PQDs in polymeric films (PQDF) with high transparency, superior photoluminescence emission and additional processing benefits for down-shifting applications. The potential use of PQDF as color converters in LCD backlights was successfully demonstrated, showing bright potential in display technology. Later on, we worked with ZHIJING TECH and other collaborators to develop the scale up fabrication of tape casting, spraying drying, extrusion melting for meeting the requirements of different applications. The PQDFs produced by ZHIJING TECH has already meet the standards for LCD-TV applications. In addition, we developed the in-situ fabrication of patterned PQDs for Micro LED and other down conversion applications. Moreover, we further explored the electroluminescence devices based in-situ fabricated PQDs. The electroluminescence devices with a maximum external quantum efficiency (EQE) of 16.3%, 15.8% and 8.8% were achieved for green, red and blue devices, showing the promising to achieve high efficiency. In all, the in-situ fabrication strategy provides very convenient route for display technology. In this talk, I will introduce the progress of in-situ fabricated perovskite quantum dots toward photonic and optoelectronic applications.

I-III-VI Quantum Dots: Optimizing Sunlight Utilization and Beyond

In recent years, I-III-VI semiconductor quantum dots (QDs) have shown significant improvements that have unlocked new capabilities and end markets. Some typical examples of I-III-VI QDs are CuAlS2 (blue), AgInS2 (green), CuInSe2 (red) CuInSe2 (near-IR), but other compositions are possible. These materials exhibit tunable photoluminescence peak emissions, with near unity quantum yield. They can have efficient broad emission, but also narrow emission, large Stokes shifts, and high optical extinction coefficients. They are more stable, safer, and lower cost than alternatives in many cases.  UbiQD, a leading materials technology and QD manufacturing company, has pioneered the industrialization and scale-up of these novel QDs, starting with critical end uses related to spectrum optimization for greenhouses and solar energy. In this presentation, UbiQD’s CEO will give an update on I-III-VI QDs as performance fluorophores, highlighting growth in exciting new markets and expanding availability of materials supply.

Shining a Light on the Future: Unlocking the Potential of SWIR Sensing with Quantum Dot Photodetectors
Various emerging technologies investigate the ability to sense and detect light in the shortwave infrared spectrum (SWIR). Autonomous cars, smart agriculture, eye tracking for AR and VR applications, face recognition, surveillance, machine vision and new microscopy techniques can take advantage of additional information found in SWIR. Thin film photodetectors, based on quantum dot photodiodes, show promise in bringing SWIR sensing to the mass markets while offering simpler and cheaper processes and higher resolution than existing technologies. In this talk we will show how imec utilizes its “one-stop shop” approach to mature this technology by taking steps towards production, industrial level qualifying, exploring new materials and demonstrating this technology in the field.

Multidimensional Quantum Dots – synthesis , unique properties and possible applications
Quantum dots exhibit extraordinary properties. However, they are currently used as colour converters in QDEFs to increase the colour gamut mainly. This is due to a lack in stability and temperature resistance. In case of the InP-based particles, also a low absorption coefficient in the blue can cause problems.
The commonly used QDs are called zero dimensional as the exciton is confined in all three dimensions. More sophisticated architectures can be achieved by fine tuning the synthesis parameters. These are 1D (rods), 2D (sheets) and 3D (giant shelled QDs). These architectures cause special properties, can solve the above mentioned problems and make new applications possible.
Here we report about the synthesis of these special types of QDs, how the oriented growth can be achieved and which properties arise from their multidimensional shape. Beside a boost in absorption in the blue and an increased stability, special properties like polarization, on/off switch ability and guided emission allow new concepts for the use of QDs especially in display applications. We will show measurements and explain, which dimensionality is useful for which application.
In addition, we will also show how this technique can be used to create QDs with a cadmium load below 2 %, but with an equal or better performance than the original CdSe/CdS/ZnS system (cd content 75 %).

X-ray Image Sensors Based on Quantum Dots
Quantum dots (QDs) constitute a photosensitive semiconductor layer applicable in various sensors. For instance, this material has recently gained prominence as an active layer in SWIR (short-wave infrared) cameras, with QDI Systems actively involved in its development. Additionally, PbS QDs demonstrate remarkable potential for efficient direct conversion X-ray detectors.
X-ray detection is a conservative field, seeking for innovations for the last 15 years aiming to reduce damaging radiation exposure for patients and enhance image quality for early diagnostics. At QDI systems, we employ an innovative approach to meet those ambitions.
Within QDI Systems, we specialize in the development of X-ray sensors based on QDs. We are pioneers in producing high-quality X-ray-sensitive QD layers, yielding promising results. Our presentation showcases the progress we have made in advancing this groundbreaking technology, including the successful integration of QD technology onto CMOS chips, resulting in compelling images.

Nano-engineered narrow-band phosphors for LED applications
Narrow-band line-emitter phosphors offer improved lm/W for white LEDs, while maintaining high CRI. Especially Eu3+-doped phosphors are ideal from an emitter perspective. However, using Eu3+ for practical LEDs is hampered by the lack of absorption in the blue spectral region. To solve this problem, we have developed nano-engineered phosphors harvesting interparticle energy transfer (IFRET), an innovative approach to sensitize Eu3+, and other ions, in the blue spectral range. In this presentation, we will share our progress on our IFRET materials, as well as demonstrate high-quality (high quantum yield and small-size) nano-YAG phosphors.

Novel LED Phosphors for the Infrared Emission Range
There is an ongoing significance of research and development (R&D) efforts in the field of narrow band LED phosphors within the visible spectral range because of unmet requirements, particularly in the cyan, green, and red spectral domains, related to shortcomings in excitability, color saturation, or luminous efficiency. Concurrently, emerging applications of novel phosphor-converted LEDs (pcLEDs) that harness the infrared (IR) spectral range, such as IR spectroscopy or medical instrumentation, often necessitate broad emission characteristics. The design of appropriate phosphors therefore mandates the exploration of unconventional phosphor host lattice properties. This presentation unveils how the strategic incorporation of disorder, and the utilization of multiple emission sites contribute to the development of effective IR phosphors catering to a wide array of spectral ranges and application domains.

Near Infrared phosphors and Applications
Phosphor-converted technology-based NIR light-emitting diodes are a compelling alternative to the conventional infrared light source due to their excellent energy-saving, mobility, and customization capabilities. Producing luminescent phosphors with different tuning structure methods is trustworthy for controlling the range of NIR regions (NIR-I, 700–1000 nm; NIR-II, 1000–1700 nm). Creating isolated luminescent centers of Cr3+ and rare-earth elements is the typical inorganic NIR phosphors design strategy. However, this strategy often fails to meet the required quantum efficiency and thermal stability due to concentration and thermal quenching mechanisms. Therefore, exploring alternative approaches to improve the performance of these phosphors is needed. NIR phosphors' luminescence properties of peak position, spectrum distribution, and thermal stability remarkably differ based on the crystal system. This talk will present a more comprehensive analysis of the local environment to improve our understanding of the luminescence properties of luminescent centers and their energy transformation.

Phosphor technology for optoelectronic applications
White light-emitting diodes (LEDs) & Laser diode (LD) as next-generation light source have significant interests owing to their outstanding characteristic such as environmental-friendly device, low energy-consumption and high brightness, compared to conventional light source. However, there are still several challenges to overcome in light applications. In this communication, we present the feasibility of phosphor ceramic for optoelectronic applications. By carefully designing the phosphor composition as well as controlling the conditions, the highly efficient phosphor ceramic (PC) is achieved. Impressively, these materials are believed to lead to excellent candidates as luminescence materials. In addition, I would like to briefly introduce phosphors for micro-LEDs.
