Abstract A novel, quick, and “clean”, method has been developed for the preparation of zinc sulfide phosphors for CRT and FED applications. The method involves the addition of a solution of sulfur in hydrazine monohydrate to a zinc salt solution, which results in precipitation of zinc sulfide, Firing this material has resulted in bright, efficient phosphors with improved luminescent properties between 500–15,000 eV, particularly for copper and silver activated ZnS.
