Welcome to Prof. Rogach
Lab at CityUHK
Welcome to the official website of Prof. Andrey Rogach, Yeung Kin Man Chair Professor in Photonics Materials at the Department of Materials Science and Engineering at City University of Hong Kong.
Our research group is dedicated to advancing chemical synthesis and application of nanomaterials. Using colloidal chemistry approaches, we synthesize nanocrystals with variable sizes, shapes, and compositions. We focus on the infrared-emitting quantum dots, as well as carbon dots and perovskites for energy harvesting and light-emitting applications.
Explore these pages to discover our main research areas, read the latest news and publications, and learn about the opportunities to join our team. If you have any questions or are interested in scientific collaboration, feel free to contact us by sending an email.
