ABSTRACT:
A zinc sulfide precursor material having axially symmetric platelet-type particles for a copper-activated zinc sulfide electroluminescent phosphor is made by reacting zinc- and copper-containing species with hydrogen sulfide and hydrogen chloride gases in a low-temperature vapor state reaction to obtain copper-containing zinc sulfide particles.
