ELECTROLUMINESCENT (EL) LAMP TO ACHIEVE HIGHER BRIGHTNESS LONGER LIFE AND MORE UNIFORM LIGHT OVER TIME

ELECTROLUMINESCENT (EL) LAMPS HAVE BEEN USED IN A NUMBER OF APPLICATIONS, PARTICULARLY IN LARGE AND SMALL DISPLAY SYSTEMS AND FOR INSTRUMENTATION LIGHTING. THESE, AND OTHER, APPLICATIONS WOULD INCREASE IF EL LAMPS COULD BE IMPROVED AS TO THEIR BRIGHTNESS, LIFETIME AND UNIFORMITY OF INTENSITY OVER TIME. PRIOR DEVELOPMENT HAS FOCUSED PRINCIPALLY ON THIN-FILM ZNS:MN DEVICES. THIS PROJECT WILL FIRST SEEK TO STABILIZE THE ACTIVE LAYER WITH VARIOUS MATERIALS FOR THE DEVICE DIELECTRICS. A NUMBER OF OXIDES WILL BE ASSESSED AS TO THEIR RELATIONSHIP TO EL DEVICE DEGRADATION. THIS ASSESSMENT WILL LEAD TO ABILITY TO RECOMMEND SUITABLE COMPOUNDS FOR THE DEVICE COMPONENTS FOR MAKING IMPROVED EL LAMPS.
