Research on Electroluminescence in Thin Film Yttria Oxysulfide
Abstract
Thin films of a rare-earth oxysulfide phosphor (Y2O2S:Eu ) were evaluated for use in a thin film electroluminescent emitter (TEL). For the first time, emission typical of the rare earth activator was observed in a rare earth host TFEL emitter. The films were characterized for optical spectrum, brightness-voltage characteristic, photoluminescence, crystal structure, and compared to efficient cathodoluminescent power phosphors (Y2O2S:Eu) as well as high efficiency TFEL emitters of ZnS:Mn. The present low intensity red emission (fractions of a ft-L) is limited by annealing induced cracks in the emitter structure.
