To improve the luminescence properties of ZnS : Cu, a multi‐doped method was used to prepare Zn(Cu 0.01 Cd 0.02 Mg 0.02 )S in this paper. As a new designed semiconductor compound, particular properties of Zn(Cu 0.01 Cd 0.02 Mg 0.02 )S were investigated, especially luminescence intensity and lifetime. Structure and compositions of Zn(Cu 0.01 Cd 0.02 Mg 0.02 )S phosphor were analyzed by XRD and TEM respectively. Luminescence intensity and luminescence lifetime of the prepared Zn(Cu 0.01 Cd 0.02 Mg 0.02 )S phosphor were investigated by luminescence spectrometry. As a result, compared with pure ZnS or doped ZnS phosphors, Zn(Cu 0.01 Cd 0.02 Mg 0.02 )S showed remarkably improved luminescence properties. The optimum ratio of three dopants was obtained for solving luminescence problems. Copyright © 2009 John Wiley & Sons, Ltd.
