Study on Preparation of Cu Doped ZnS Nano-phosphor Powder by Chemical Synthesis

ZHANG Hai ming,WANG Zhi jian,ZHANG Li gong,LI Yu qin,YUAN Jin shan (Institute of Optics,Fine Mechanics and Physics,Chinese Academy of Sciences,Changchun 130021,China) (Received 6 March 2002,accepted 15 July 2002)  
In this paper,we described a new method for preparation of Cu doped ZnS nano phosphor powder. The size of the particles can be easily controlled by adjusting the molar ratio of the mercaptoacetic acid to monomer of the methacrylic acid. The transmission electron microscope (TEM),X ray powder diffraction (XRD) and photoluminescence (PL) are used to characterize the structure of this nanopowder.The chemical synthesis method can be easily extended to prepare other metal doped ZnS nanopowder.
