Ultrafast carrier dynamics in spherical CdSe core/elongated CdS shell nanocrystals

摘要

The ultrafast carrier dynamics in CdSe/CdS dot/rod nanocrystals have been investigated by sub-ps-pump-probe experiments in the visible spectral range. Photobleaching dynamics due to state filling is explored and a picture for the electron-hole dynamics at the interface, within the nanostructure, is obtained.
