Abstract:

A procedure was developed for producing an electroluminescent thin film of Mn activated ZnS by a one-step process of coevaporation of a mixture of ZnS and Mn metal powder. GeO2 was a satisfactory dielectric layer compatible with the phosphor. Evaporated Al and Mo were satisfactory for the top electrodes. Mo offered an optical advantage in that a film which was semitransparent in the visible range could be used. A d.c. bias superimposed on a pulsed signal was observed first to decrease the emission intensity of the thin film electroluminescence, then after a certain threshold value had been reached to increase the emission intenstiy through an ac-dc enhancement effect.
