ABSTRACT:
Electroluminescent display panels comprising copper sulfide coated Zns:Mn phosphor powder, bonded in an organic dielectric binder, can be provided with increased useful lives by incorporating (1) silver in the copper sulfide coating on the ZnS:Mn phosphor powder, in an amount of 2 to 12%, by weight of the copper in the copper sulfide coating; and (2) elemental sulfur in the dielectric binder, in an amount of 0.1 to 3%, by weight of the phosphor particles. The additives can be used independently or together, preferably together. Methods of incorporating the additives are also disclosed.
