Abstract
Coated CdSe/CdS nanocrystals have been synthesized through a new reaction routine in micelle solution. High-resolution transmission electron microscope (HRTEM) images demonstrated the monodispersity and core-shell structure of CdSe/CdS nanocrystals. After CdSe nanocrystals were passivated by CdS shell, the reduced photoluminescence (PL) intensity of surface states and enhanced band-edge emission have been observed. The enhanced photo-chemical stability of coated CdSe/CdS nanocrystals has also been demonstrated from photo oxidation experiments.
