Microemulsion Improvement Method Preparation of ZnS and Luminous Performance Research

Abstract

Series samples ZnS and ZnS: Cu2+(0.001<x<0.05) have been prepared by a simple and template-free microemulsion improvement method. From the XRD we know that all samples are single phase. The SEM photo shows that the particle sizes are about 20nm~50nm.When the contents of doping Cu2+ ions increasing, the particle sizes become larger, which proves that Cu2+ ions occupy the position of Zn2+ ions. The emission spectrum (ES) indicates that when doping Cu2+ ions ,samples show a blue light and the main emission peaks which caused by Cu2+ ions t2 transition locates at 425nm.
