Surface-related emission in highly luminescent CdSe quantum dots
by Wang, Xiaoyong; Qu, Lianhua; Zhang, Jia-Yu; Peng, Xiaogang; Xiao, Min
We report our experimental studies of surface-related emission in highly luminescent CdSe quantum dots (QDs) with controlled quantum yield and photooxidation by time-resolved photoluminescence measurements. This kind of surface-related emission, with a radiative lifetime of tens of nanoseconds, implies the involvement of surface states in the carrier recombination process of such highly luminescent CdSe QDs.
