Microemulsion Method Preparation Zn<sub>(1-X)</sub>S:Cu<sub>x</sub>(0.001<x<0.05) and the Research of Luminescence Property

Abstract

Series samples Zn(1-x)S:Cux (0.001<x<0.05) have been prepared by a simple and template-free microemulsion method. From the XRD we know that all samples are single phase. The SEM photo shows that the particle sizes are about 50～200nm.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. Moreover, when co-doping Cu2+ ions and Mn2+ ions, the intensity of PL emissions increased.
