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.
