Abstract :
Mercaptoacetic acid (MMA)-capped ZnSe (ZnSe–MMA) core–shell nanocrystals have been prepared by two-step hydrothermal method using Se and Zn(NO3)2 aqueous solution as precursor. The as-prepared ZnSe are zincblende structure with grain size of 4 nm. The MMA-capped ZnSe nanocrystals are more stable and can be preserved long time without oxidation in the air. The ZnSe–MMA core–shell nanocrystals show good absorption for the ultraviolet light.
