Abstract: In this study, we find that KrF excimer laser irradiation is an effective treatment for enhancing polymer light-emitting diode (PLED) performance, due to the increase in work function and the amount of oxygen on the indium–tin oxide (ITO) surfaces and the reduction in ITO surface roughness, resulting in a reduction in leakage current at the polymer/ITO interface and an increase in device luminance. It is indeed necessary to minimize the leakage current to prevent unnecessary wasting of power and to increase external quantum efficiency.
