Abstract

We studied the optimum layer configurations for high efficiency phosphorescent OLED through dopant concentration control when the electron injection rate of ETL is increased with the addition of ZnO nanoparticles. It was found experimentally that the lr(ppy)3 dopant concentration of 5wt% was optimized to show the best luminance over 8,200cd/m2
