Prof. Dr. Andrey ROGACH

City University of Hong Kong, Čína

Specialization: Quantum dots and metal nanocrystals

A. Rogach received his diploma in Chemistry from the Belarusian State University in Minsk (Belarus) in 1991. In 1995 he received PhD from this university focused on „Formation and properties of silver nanoparticles in different media“. In the period 1995-2002 he worked as a research scientist at the Institute of Physical Chemistry, University of hamburg (Germany), in the period 2002-2009 as lead scientist of the Photonics and Optoelectronics Group at the Center for NanoScience, Ludwig-Maximilians-Universität München (Germany). In 2009 habilitation in Physics at the Center for NanoScience on „Light emission and harvesting with semiconductor nanocrystals: Synthesis, spectroscopy and applications“. Since 2009 he is a professor and founding director fo the Centre for Functional Photonics at City University of Hong Kong.Since 2011 he acts as an associate editor of ACS NANO web platform.

He is co-author of more than 200 scientific publications with a total number of citations (Web of Science) exceeding 11000 (October 2011), h-index (Hirsch factor) of citation 57 (October 2011). He has been Ranked 8th in the "TOP AUTHORS publishing on nanocrystals in the past decade"and Ranked 51st among top 100 Materials Scientists in the World

Nanotechnology Research

Using the colloidal chemistry approaches Prof. Rogach and his research team synthesize semiconductor and metal nanorystals of variable sizes, shapes and compositions, tuning the emission of semiconductor nanocrystals and surface plasmon resonances of metal nanoparticles through the visible and near-IR spectral range. They apply optical spectroscopy to study energy transfer and charge separation in these nanostructures and look for different applications of semiconductor and metal nanocrystals, ranging from photovoltaics and water splitting to biological fluorescent labels and SERS substrates.
