Rogach, Andrey L. - 香港城市大学

个人简介

Andrey L. Rogach is a Chair Professor of Photonics Materials at the Department of Physics and Materials Science and the Founding Director of the Centre for Functional Photonics (CFP) at City University of Hong Kong. He received his Diploma in Chemistry (1991, with honors) and Ph.D. in Physical Chemistry (1995) from the Belarusian State University in Minsk studying formation and properties of silver nanoparticles in different media. He worked as a postdoc (with Horst Weller) and then as a staff scientist at the Institute of Physical Chemistry of the University of Hamburg, Germany from 1995 to 2002. From 2002–2009 he held a tenured position of a lead staff scientist at the Department of Physics and Centre for NanoScience of the University of Munich, Germany, where he completed his habilitation in Experimental Physics on light emission and harvesting with semiconductor nanocrystals. He joined City University of Hong Kong as a Full Professor in 2009 and has been advanced to Chair Professor in 2012. His research focuses on synthesis, assembly and optical spectroscopy of colloidal semiconductor and metal nanocrystals and their hybrid structures, and their use for energy-related applications. He authored over 300 scientific publications (h-index: 83) in these fields that have been extensively (over 25,000) cited, which ranked him 8th worldwide among “20 TOP AUTHORS publishing on nanocrystals in the past decade” by Thomson Scientific, Essential Science Indicators (2007) and 51st worldwide among “100 TOP MATERIALS SCIENTISTS OF THE PAST DECADE” by Thomson Reuters (2011). His distinctions include the DAAD (Germany, 1995) and the Alexander von Humboldt (Germany, 2000) Fellowships, British Telecom (UK, 1998) and NRC COBASE (USA, 1999) Fellowships, the Walton Award from the Science Foundation Ireland (2005), the Grand Research Excellence Award from City University of Hong Kong (2011), and the Ikerbasque Fellowship of the Basque Country (Spain, 2012). He holds honourable appointments as an Adjunct Professor at Trinity College Dublin (Ireland) and University of Electronic Science and Technology of China, and as a Honorary Professor at Xi’An Jiaotong University, Jilin University, and Peking University (China), and has been a Visiting Professor at Nanyang Technological University of Singapore. Andrey Rogach is a Fellow of the Electromagnetic Academy (USA) and serves as an Associate Editor of ACS Nano.

研究领域

Using colloidal chemistry approaches, we synthesize nanocrystals of different materials (semiconductors, metals, oxides) of variable sizes, shapes and compositions. We currently focus on infra-red emitting II-VI semiconductor nanocrystals; as well as carbon dots, perovskite nanocrystals and metal nanoclusters emitting in the visible spectral range. We widely apply photoluminescence spectroscopy to study light emission, energy transfer and charge separation in composite structures containing those kinds of nanoparticles, and explore their different applications such as light-emitting devices and photodetectors.
