Colloidal chalcogenide-based nanocrystals are among the first quantum dots reported and now considered as one of the most efficient materials for optoelectronic applications in the visible and infrared (IR) range. This symposium invites contributions from the field of colloidal nanocrystals and quantum dots which are based on metal chalcogenides (S, Se, Te). We welcome all relevant material classes, such as, for example, binary II-VI, ternary I-III-VI and other more complex material compositions. We wish to cover a broad range of applications from visible to IR in photovoltaics (solar cells), light-detection (photodetectors), and light-emission (light-emitting diodes), among other optoelectronic devices or light-matter interactions. We aim to cover all related aspects of chalcogenide-based nanocrystals from chemical synthesis, study of their properties, ink formulation, material deposition, device fabrication, performance optimization as well as stability and end-of-life assessment.
By bringing together an interdisciplinary expertise, we will discuss the recent developments, latest breakthroughs, open challenges and future directions of this exiting class of materials.

Short Bio: Dr. Beatriz H. Juárez graduated in Chemistry from the Complutense University of Madrid and obtained her PhD in Materials Science in 2005. After an industrial position at Lucent Technologies (Madrid), she pursued postdoctoral research with Horst Weller at the University of Hamburg, where she was awarded a European Individual Marie Curie Fellowship (EIF). She subsequently held a tenure-track position "Ramón y Cajal" at IMDEA Nanoscience (Madrid) and, in 2012, was appointed Associate Professor at the Department of Applied Physical Chemistry, Autonomous University of Madrid (UAM). Since 2021, she is Tenured Scientist at ICMM–CSIC (National Spanish Research Council). She also serves as a member of the Materials Science Panel of the Spanish National Research Agency (AEI) since 2023. Her research centers on semiconductor nanoparticles, colloidal quantum dots, and advanced nanostructured hybrid systems
Tsukasa Torimoto is a professor at the Graduate School of Engineering and the Research Institute of Quantum and Chemical Innovation, Nagoya University, Japan. He received his Ph.D. in Engineering from Osaka University in 1994. His research focuses on the synthesis and functionalization of semiconductor quantum dots and metal nanoparticles. In particular, he has extensively investigated low-toxicity multinary semiconductor quantum dots, with an emphasis on precise control over their composition, size, shape, and interfacial structures to tailor their optical and photoelectrochemical properties. He also explores the applications of these quantum dots in luminescent materials, photocatalysis, photovoltaics, and bioimaging. He has received several awards, including the Japanese Photochemistry Association Award and the Scientific Achievement Award of the Electrochemical Society of Japan. He was elected a Fellow of the Electrochemical Society of Japan in 2020.
Dr. Yana Vaynzof is the Chair for Emerging Electronic Technologies at the Technical University of Dresden (Germany) and a Director at the Leibniz Institute for Solid State and Materials Research Dresden. She received a B.Sc. in Electrical Engineering from the Technion – Israel Institute of Technology (Israel) in 2006 and a M. Sc. In Electrical Engineering from Princeton University (USA) in 2008. In 2011, she received a Ph.D. in Physics from the University of Cambridge (UK). Yana was a postdoctoral research associate at the Cavendish Laboratory, University of Cambridge (UK) and an assistant professor at Heidelberg University (Germany) from 2014 to 2019. Yana Vaynzof is the recipient of a number of fellowships and awards, including the ERC Starting Grant, ERC Consolidator Grant, Gordon Wu Fellowship, Henry Kressel Fellowship, Fulbright-Cottrell Award and the Walter Kalkhof-Rose Memorial Prize. She is a Fellow of the Royal Society of Chemistry and the winner of the Energy & Environmental Science Lectureship Award. Her research interests lie in the field of emerging photovoltaics, focusing on the study of material and device physics of organic, quantum dot and perovskite solar cells by integrating device fabrication and characterisation with the application and development of advanced spectroscopic methods.
David WegnerMark W.B. Wilson (he/him) is an Associate Professor in the Department of Chemistry at the University of Toronto, where his team strives to understand the synthesis, structure, and photophysics of colloidal quantum dots (and functionalized, hybrid architectures) to advance their use in photonic & optoelectronic applications. A present focus is advancing nanocrystal-sensitized triplet-fusion upconversion. His first degrees were in Engineering Physics and History at Queen’s University (Kingston). He next received a PhD in Physics (2012) from the University of Cambridge under the supervision of Prof. Sir Richard Friend. Then, as a member of the Centre for Excitonics at the Massachusetts Institute of Technology, he pursued postdoctoral studies (2012-2016) with Prof. Moungi Bawendi (Chemistry), before starting his independent career.
