BrightLeave™ Perovskite QD Films As X-ray Scintillators
Perovskite quantum dots (PQDs) can improve applications from displays to scintillators because of their superior light-emitting properties compared to classical quantum dots. Standing in the way of these applications is the difficulty to process PQDs into devices, especially into the polymer thin films used in displays and scintillators, without losing their unique properties. BrightComSol presents BrightLeaf™, a flexible perovskite-based scintillator based on a new resin, BrightSplash™. Our resin allows for the efficient processing of PQD flexible films at low and high loading. We share recent highlights of using BrightLeaf™ for high-resolution X-ray imaging.

Head of Dept. Organic Micro Devices @ Fraunhofer FEP
Bernd Richter (male) born 1977, received his diploma in electrical engineering from TU Dresden in 2003 with the focus on information technology and microelectronics. After graduation he became a research fellow at Fraunhofer IPMS in Dresden in the field of system and integrated circuit design where he specialized in the design and manufacturing of OLED microdisplays and sensors based on the organic-on-silicon technology. In 2010 he became head of the research group „Microdisplay Devices and Systems“. After the changing to Fraunhofer COMEDD in 2012 he headed the core competency „IC und Systemdesign“, that was transferred into the department „IC und Systemdesign“ at Fraunhofer FEP in 2014. In the further course he redeployed his R&D focus into the direction of technology and integration of organics on silicon wafers. In 2017 he became head of the department „Organic Microelectronic Devices“. Bernd manages several industrial and research projects in the field of data glasses, microdisplays and sensors at national and international level and is deputy head of the business unit "Microdisplays and Sensors".

Division Director | Functional Polymer Systems @ Fraunhofer IAP
Dr. Armin Wedel studied Physics at the University of Rostock from 1981 to 1986. In 1992 he received the Ph.D degree in Physics at the University of Potsdam. From 1986 until 1991 he works as a scientific research assistant at the Institute of Polymer Chemistry of the Academy of Science in Teltow. Since 1992 he works at the Fraunhofer Institute for Applied Polymer Research in several research positions. He was a member of research group of physically active polymers with the topic of nonlinear optical properties of side-chain polymers and works as a research assistant in the field of OLEDs, OTFTs and OPV. Now he is responsible for the development of the technology of organic light emitting diodes (OLED) from the layout to the encapsulation and organic photovoltaic in several applications. Since 2006 he is head of the Department of Functional Materials and Devices at the Fraunhofer Institute for Applied Polymer Research and Division Director of Functional Polymers. Since 2009 he is involved in the development of environmentally friendly quantum dot materials as a new class of emissive materials for future display and lighting applications. He holds more than 18 patents, 70 publications in various journals. In 2012 he received an award of the Korean Society Display (Korean Information Display Society) for outstanding achievements in the field of synthesis and application of environmentally friendly quantum dots (QD) for display technology. He is the President of the German Flat Panel Forum (DFF e.V.) since 2020 and member of the overseas advisory boards of the International Conference on Display Technology (ICDT), China and of the International Meeting on Information Displays (IMID), Korea.

Red Perovskite Emitters for Colour Conversion and LEDs
Perovskites are promising light-emitting materials for colour conversion and direct electroluminescence with the potential to enable advanced display architectures. While early commercial development has focused on green, red emitters are needed for both in-pixel and backlight film colour conversion. Here we report on the recent developments on red emitters tailored for wide-colour gamut and power efficiency. The materials show very high colour stability and are suitable for use in films, pixels, and LEDs.
High Pixel Density Infrared Sensors Enabling Augmented Vision
Image sensors using quantum dots as the photoactive layer have the potential to disrupt imaging and sensing, especially at wavelengths beyond the spectrum accessible by silicon. Thanks to monolithic integration directly on the readout circuit, pixel pitch can be scaled down and resolution can be maximized. Imec is developing technologies for short-wave infrared (SWIR) image sensors, focusing on compatibility with CMOS fab processing. Focal plane arrays with pixels smaller than 2 um are demonstrated, showing a route towards miniaturization of SWIR cameras. This technology enables introduction of infrared vision into applications that traditionally could not afford that.
