Research on Photoluminescence Characteristics of the Active Cl-Doped ZnS
A active Cl-doping for photoluminescent ZnS powder has been carried out by thermal decomposed AlCl3·6H2O in a quartz tube. Room temperature photoluminescence of the Cl-doped ZnS powder has been investigated using a photoluminescence spectrometer with 365 nm excitation wave length. A strong blue photoluminescence with maximum peak about 450 nm and green photoluminescence with maximum peak about 500 nm can be observed if the doping temperature in range of 800 ~ 900 °C and 1100 ~1200 °C, respectively. The structural characterizations of the Cl-doped ZnS powders were performed with X-ray diffraction (XRD) and the mechanism of photoluminescence was preliminarily discussed.
