摘要：

Described herein is a novel one-pot aqueous synthesis of ZnSe nanocrystals has featuring the utilization of Na2SeO3 and Zn(AC)(2)center dot 2H(2)O as Se and Zn source, glutathione (GSH) as stabilizing agent and reducing agent. By this approach, the UV-blue ZnSe QDs with quantum yield (QYs) up to 19% have been synthesized with a molar ratio of Se/Zn/GSH at 1:4:8.5 under aqueous conditions at 110 degrees C. XRD and TEM show the ZnSe QDs are zinc cubic structure particles with an average diameter of 3-5 nm.
