ABSTRACT:
A method of coactivating a rare earth activated, electroluminescent zinc sulfide film with activator gas is described. The phosphor film is deposited upon a substrate by co-sputtering from a zinc sulfide target and a rare earth target in an atmosphere such as hydrogen, chlorine, fluorine or bromine, and an inert gas.
