This symposium invites contribu ons discussing progress in research and technology of quantum dots (QDs) made of III-V semiconductors. Such QDs are compliant with restric ons on hazardous substances (RoHS), and are currently inves gated for any applica on involving light-ma er interac on. The symposium will cover the fundamental chemistry and physics of III-V QDs, with room for experimental and computa onal approaches, and the latest developments in III-V QD-technology. This includes, but is not limited to ques ons of III-V QD synthesis, surface chemistry, electronic structure and op cal proper es, and applica ons of III-V QDs in display, ligh ng and infrared imaging. The symposium is open to contribu ons exploring RoHS-compliant QDs with different composi on.

Prof. Z. Hens received his PhD in applied physics from Ghent University in 2000, worked as a postdoctoral fellow at Utrecht University and was appointed professor at the Ghent University department of inorganic and physical chemistry in 2002. His research concerns the synthesis, processing and characterization of colloidal nanocrystals.
Dr. Francesco Di Stasio obtained a Ph.D. in Physics at University College London (UK) in 2012. He then worked as a research Scientist at Cambridge Display Technology (Sumitomo Chemical group, UK) until he undertook postdoctoral research at the Istituto Italiano di Tecnologia (IIT, Italy). In 2015 he was awarded a Marie Skłodowska-Curie Individual Fellowship at the Institute of Photonic Sciences (ICFO, Spain). Since 2020 he is Principal Investigator of the Photonic Nanomaterials group at IIT after being awarded an ERC Starting grant. Francesco is a materials scientist with more than 10 years of research experience in optoelectronics.
Current research interests and methodology: Nanomaterials for classical and non-classical light-sources: This research activity focuses on the investigation of synthetic routes to obtain highly luminescent semiconductor colloidal nanocrystals and exploit such material in light-emitting diodes (LEDs). Here, we study how chemical treatments of colloidal nanocrystals can promote enhanced performance in devices, and physico-chemical properties of nanocrystals (e.g. self-assembly and surface chemistry) can be exploited to fabricate optoelectronic devices with innovative architectures. Novel methods and materials for light-emitting diodes: The group applies materials science to optoelectronics by determining which fabrication parameter lead to enhanced performance in LEDs. In order to transition from classical to non-classical light-sources based on colloidal nanocrystals, the group is developing novel methods for controlling the deposition and positioning of an individual nanocrystals in the device. Both “top-down” and “bottom-up” approaches are investigated.
Arjan Houtepen obtained his PhD Cum Laude under supervision of prof. Vanmaekelbergh at Utrecht University and subsequently became tenure track assistant professor in Delft. In 2009/2010 he was a visiting scientist in the group of prof. Feldmann in Munich. At present he is associate professor in the optoelectronic materials section at Delft University.
Juliette Zito received her PhD in Chemistry from the University of Genoa (Italy) in 2023. Her doctoral research was carried out at the Italian Institute of Technology (IIT) under the supervision of Ivan Infante and Liberato Manna, focusing on the development and application of computational tools for the atomistic description of semiconductor colloidal nanocrystals. She is currently an FWO Junior Postdoctoral fellow at the Electron Microscopy for Materials Science (EMAT) group of the University of Antwerp, where she combines molecular modeling techniques with quantitative electron microscopy to achieve atomistically precise 3D reconstructions of semiconductor nanocrystals. As part of the FWO fellowship, she also collaborates with the Center for Molecular Modelling (CMM) of the University of Ghent, focusing on the development of machine learning potentials (MLPs) for semiconductor nanocrystals.
