Abstract

Effects of Rb doping on the aging characteristics have been studied in SrS:Ce thin film electroluminescence (EL) devices. It has been found that a luminance saturation and decrease of an EL efficiency are suppressed by Rb doping. For the SrS:Ce,Rb device, a luminance and an efficiency after 1024 h of aging at 1 kHz drive maintain at about 70% and 80% of the initial values, respectively.
