Colloidal I-III-VI nanocrystals and their derivatives are emerging as eco-friendly next-generation materials for light-emitting and light-harvesting applications. This symposium will bring together researchers working across synthesis, spectroscopy, theory, and device integration of colloidal I-III-VI nanocrystals and related systems to discuss recent advances and challenges in the field. Topics include controlled synthesis strategies for pristine, alloyed, and nonstoichiometric compositions; heterostructures, and core-shell architectures; and fundamental studies of defects, excited-state dynamics, and radiative and nonradiative recombination pathways. Emphasis will be placed on structure-property relationships that direct whether emission arises from band-edge or sub-gap defect states, and the role of composition, surface ligands, and stoichiometry in tuning these behaviors. The symposium will also cover applications in LEDs, luminescent solar concentrators, photocatalysis, solar energy conversion, lasing, and amplified spontaneous emission. Contributions employing advanced spectroscopic approaches to probe charge and energy transfer processes in assembled and hybrid systems, are equally encouraged.

Matthias KickLazaro PadilhaPeter Reiss is researcher at the Interdisciplinary Research Institute of Grenoble (IRIG), France, and Head of the Laboratory Synthesis, Structure and Properties of Functional Materials (STEP). He graduated from University of Karlsruhe (Germany), and earned his PhD in Inorganic Chemistry under the supervision of Prof. Dieter Fenske (2000). His research activities focus on the synthesis and properties of colloidal semiconductor quantum dots and metal halide perovskites (nanoparticles and thin films). The studied applications range from biological imaging / detection over LEDs and displays to new strategies for energy conversion (photovoltaics, thermoelectrics, photocatalysis) and storage. Dr. Reiss acts as Associate Editor for Nanoscale Research Letters and Frontiers in Materials - Energy Materials, and is Editorial Board Member of Scientific Reports. He co-organizes the biennial conference NaNaX – Nanoscience with Nanocrystals (cf. http://nanax.org).
Vanessa Wood is a professor in the Department of Information Technology and Electrical Engineering at ETH Zurich, where she heads the Laboratory for Nanoelectronics. Before joining ETH in 2011, she was a postdoctoral associate in the laboratory of Professor Yet-Ming Chiang and Professor Craig Carter in the Department of Materials Science and Engineering at MIT, performing research on novel lithium-ion battery systems. She received her MSc and PhD from the Department of Electrical Engineering and Computer Science at MIT. Her graduate work was done in the group of Professor Vladimir Bulović and focused on the development of optoelectronic devices containing colloidally synthesized quantum dots.
Maksym Yarema received his master degree in Chemistry from Lviv National University (Ukraine) in 2007. From 2008 to 2012, he worked towards his doctorate degree at the Johannes Kepler University Linz (Austria) under supervision of Prof. W. Heiss. In 2012, he joined the research group of Prof. M. V. Kovalenko at EMPA as Marie-Curie fellow. Since 2013, he is working in the Institute for Electronics, ETH Zurich (the research group of Prof. V. Wood), where he received the SNSF Ambizione Fellowship in 2016 and the ERC Starting Grant in 2019.
