Benefiting from their quantum confinement effect, semiconductor quantum dots and nanocrystals present strange photophysical properties and have important application prospects in light emission devices, solar cells, photodetectors, etc. On the other hand, the large specific surface area of nanocrystals leads to their photophysical properties being extremely sensitive to the environment. Therefore, revealing the microscopic mechanism of semiconductor nanocrystals' light emission, developing corresponding regulation and enhancement techniques, and preparing efficient nanodevices are of great significance to further expand the application of semiconductor nanocrystals. At present, our research contents include: (1) Investigating the exciton dynamics of semiconductor quantum dots and perovskite nanocrystals, including single excitons, double excitons, and charged excitons; (2) Enhancement of fluorescence emission behavior of semiconductor nanocrystals by metal microcavity; (3) Preparation of semiconductor nanodevices, including quantum dot microflow lasers, perovskite solar cells and photodetectors.
