The initial phase of a program investigating rare-earth-activated zinc sulfide ZnS for various display applications is described. Theory on the mechanisms of activator and sensitizer incorporation and energy transfer is discussed. Detailed descriptions on the synthesis and analysis of ZnSEr,Cu are included. The emission and excitation spectra are described and certain conclusions are drawn concerning the phosphor mechanisms from these spectra. The phosphors synthesized are quite bright and efficient and have the indicative rare-earth, narrow-emission spectrum. ZnSEr,Cu emits mainly in a narrow band around 530 nm, which has a high luminous equivalent, and has a peak intensity more than twice that of commercially obtained P2. This luminescent system shows good promise for display applications. Author
