Artur Podhorodecki graduated from Wrocław University of Science and Technology with a specialization in Solid State Physics. In 2007, he completed his doctoral studies with honors. His dissertation earned him the Prime Minister’s Award for the best doctoral thesis in the field of Materials Engineering. In 2020, he was awarded the title of Professor of Physical Sciences.
He is the co-author of 130 scientific publications and 9 patents or patent applications and has received numerous awards and fellowships for his research. He is an expert in optical spectroscopy of semiconductor nanostructures as well as in the synthesis and functionalization of inorganic nanomaterials.
He is the CEO and founder of QNA Technology S.A., a company specializing in the synthesis and modification of heavy metal-free, blue-light-emitting semiconductor quantum dots, and the development of inks based on these nanomaterials for applications in displays and photonics.
One of the intriguing yet largely unexplored technological approaches to fabricating microLED displays involves utilizing UV microLEDs alongside colloidal quantum dots as light-converting materials. A main difference from traditional blue LEDs backlighting lies in the necessity of integrating hard-to-make and hard-to-get blue QDs in addition to red and green QDs. Despite this challenge, this approach offers several significant advantages, such as the lack of blue light leakage or better absorption efficiency of red and green QDs in the UV range as to name the most important ones.
In this presentation, we will show the properties of our UV curable inks, which are based on heavy metal-free, blue light-emitting QDs known as PureBlue.dots, which can be used for UV light conversion to high quality 455 nm blue light which can be used in microLED displays.
Furthermore, we will showcase our recent findings obtained from electroluminescent devices utilizing PureBlue.dots as the active material.

Manuel Gensler is a physical chemist (diploma, HU-Berlin) and chemical physicist (PhD, HU-Berlin) with research interests in functional materials (polymers and nanomaterials), solution processing of devices (OLED, OPV, Perovskites), and single-molecule physics. During his scientific projects, he gained deep knowledge in printing technologies (Ink-Jet, EHD-Jet) and atomic force microscopy (AFM). Thereby, he worked with a broad range of materials: single (bio)polymers, organic materials, thin films, 2D materials such as graphene, supported lipid bilayers, and nanomaterials such as quantum dots. Since 2017, he has been working as a project manager and, since 2023, as a research manager at Fraunhofer IAP. In his leisure time, he is treasurer of the non-profit organization Chemie Freunde Erkner e.V., which aims to bring science and especially chemistry to a general audience. A special focus is on experiments for children. For these activities, he received civic awards from the city of Erkner in 2013 and 2022.
(Fraunhofer IAP, Germany)
Sören Becker studied chemistry at the University of Hamburg. Since his diploma and PhD thesis in the research group of Prof. Dr. Horst Weller in 2009, he has worked on the synthesis and modification of nanoparticles. When he joined the Centrum für Angewandte Nanotechnologie (CAN) GmbH in 2016, he specialized in the synthesis and modification of quantum dots. In January 2018, CAN GmbH joined the Fraunhofer-Gesellschaft and became the 7th research division of the Fraunhofer Institute for Applied Polymer Research (IAP) which is still located in Hamburg. As a member of the Quantum Materials department, he focuses on the synthesis, modification, and application of quantum dots in display and lighting technologies. He is particularly interested in quantum dot systems with large-volume shells.
Quantum Dot (QD) materials are emerging as promising candidates for color conversion in a micro-LED display, offering significant advantages over traditional RGB emitting backplanes. This talk presents Fraunhofer IAP’s recent advancements in QD technologies for microLED color conversion. Key developments include the enhancement of QD photostability through optimized ligand engineering and ALD-based film encapsulation, as well as improved quantum yield using giant-shell structures. To address the absorption limitations of InP-based QDs in the blue spectral region (around 467 nm), doping and shell engineering strategies were employed to boost light absorption and overall conversion efficiency. Furthermore, high-resolution patterning of QDs was demonstrated using electrohydrodynamic (EHD) jet printing, achieving sub-10 µm resolution on multi-nozzle systems. These integrated approaches offer scalable, RoHS-compliant solutions for the next generation of efficient and reliable microLED displays. In addition, recent developments in QD electroluminescence (QD-EL) devices using IAP-developed materials will also be briefly highlighted.

Peter Palomaki is the owner and chief scientist at Palomaki Consulting, LLC where he consults with companies around the world on understanding, characterizing, and implementing QD and other nanomaterial technologies. He holds a Ph.D. in chemistry from Rensselaer and has developed QD-enabled optical technologies at National Renewable Energy Laboratory along with multiple companies, including QD Vision. He has become a trusted speaker, writer, and QD industry veteran, relied on by clients for his problem-solving capabilities and deep network in the display industry.
Maturation of QDs in displays has led to several implementation methods using QDs as down-converters, each with their own advantages, drawbacks, and challenges to implementation. QD films, extruded plastic diffusers, and QD inks directly on top of OLED pixels have all become commonplace in displays. As the regulatory landscape and technical requirements evolve, QDs must evolve. This talk will provide a commercial and regulatory status update of QDs in display and how the implementations vary in their QD requirements.
