Title:  Light-Emitting Colloidal Nanostructures

Speaker: Andrey L. Rogach, Department of Materials Science and Engineering & Centre for Functional Photonics, City University of Hong Kong

Time: 3rd May，2018 ，15:00 p.m

Place: Room 104，Building 1，State Key Laboratory for silicon materials，Yuquan Campus

Inviter: Prof. Xiaodong Pi

Abstract:

I will provide an overview on several kinds of light-emitting colloidal nanostructures synthesized in our labs, which include infared emitting CdHgTe and HgTe quantum dots; red/infrared emitting carbon dots; and copper clusters based composite materials. I will highlight the correlation between the structural characteristics of carbon dots and perovskite nanocrystals and their optical properties studied by advanced optical spectroscopy techniques,and demonstrate their emerging applications such as luminescence nanothermometry.
