The luminescence characteristics of ZnSxSe1−x phosphor powder

In this study, the effects of processing on the phosphor characteristics of ZnSxSe1−x powder were performed. The ZnS used in this experiment is a green light powder, and the ZnSe is a red light powder. Phosphor powder with green light to red light emission can be obtained using mixtures of ZnS and ZnSe with different ratios. Results indicated that prolong the soaking time of the mixtures at 1000-1100 °C, a better luminescent intensity is obtained. It is due to the oxygen enters into ZnSSe lattice, which results in the distortion of the crystal lattice and the formation of the crystal defects.
