ABSTRACT:
Flake-like ceramic particles of zinc sulfide phosphor and method of preparing the same including the steps of preparing flake-like particles of basic zinc sulfate crystal doped with activator, sulfurizing in the particles carbon disulfide, and heating the sulfurized particles in hydrogen sulfide. Particularly by steeping said particles in a solution of alkaline earth metal salt prior to or after sulfurizing, grain growth in ceramic particles can be improved.
