"Insights into the History of Colloidal Quantum Dots – a European Perspective" by Prof Andrey Rogach | IAS STEM Graduate Colloquium

30 Apr 2024 02.00 PM - 03.30 PM SPMS LT2 Alumni, Current Students, Industry/Academic Partners, Prospective Students, Public

Join us in the IAS STEM Graduate Colloquium on 30 April 2024 (Tue), 2pm at SPMS LT2 by our distinguished speaker, Prof Andrey RogachFounding Director of the Centre for Functional Photonics & Yeung Kin Man Chair Professor of Photonics Materials , City University of Hong Kong 

About the talk

The 2023 Nobel Prize in Chemistry was awarded to Moungi Bawendi, Louis Brus, and Alexei Ekimov, for the discovery and synthesis of quantum dots (QDs). According to Brus, “This was a collaborative effort, it’s partly physics, partly chemistry and partly material science”.

Since their discovery in the early 1980s, QDs remain a paradigmatic example of the size-dependent properties characteristic of nanoscale materials, and served as a workhorse to promote research and development in the field. Their unique electronic and optical properties can be exquisitely tuned by controlling particle size, setting a high standard for nanomaterial tunability and control. 

A comprehensive review by Efros and Brus in ACS Nano traces the QDs evolution, from their inception in glasses to their advancement through colloid science-based wet-chemistry methods, and their applications in many fields, ranging from fluorescent bioimaging to light emitting diodes, solar cells, and QD TVs. In this talk, I will offer personal insights into the earlier developments of QDs, from a perspective of a scientist who entered this field in Europe in the mid-1990s.

Our Distinguished Speaker

Prof Andrey Rogach's research focuses on the synthesis, assembly and optical spectroscopy of colloidal semiconductor and metal nanocrystals, alongside their hybrid structures and applications in energy-related and optoelectronic fields. He has been recognised as a highly Cited Researcher by Clarivate Analytics continuously since 2018. 
He received his PhD in Physical Chemistry from the Belarusian State University focusing on silver nanoparticles in different media. He worked as a postdoc and then as a staff scientist at the University of Hamburg, before joining the University of Munich as a tenured lead staff scientist. He joined City University of Hong Kong as a Full Professor in 2009 and was promoted to Chair Professor in 2012
