Effect of shock wave processing on the properties of ZnS and ZnS-based phosphors

This paper describes a process for shock wave processing of ZnS powder in a closed protective metallic ampule wrapped in an explosive sheet, which is exploded to generate a shock wave. The process enables control over the shock wave energy delivered to ZnS. The method is used for ZnS preprocessing in the synthesis of zinc sulfide phosphors. The effect of shock wave processing on the particle size and crystal structure of ZnS is examined. The processing conditions are optimized so as to increase the brightness of the phosphors fabricated from the zinc sulfide.
