Laser modulation of electroluminescence in thin-film ZnS: Mn devices

View publication

Abstract

Large photoenhancement (by a factor of ≳100 in some devices) of electroluminescence in thin-film ZnS: Mn devices has been observed near and above the electroluminescence threshold effects when the devices were excited with the near-uv lines of an Ar+ laser. The intensity of the photoenhanced electroluminescence was found to have a sublinear dependence on the laser intensity, saturate, and then decrease with increased laser power.
