Abstract

We report optimization methods of charge trapping and doping concentration in an emission layer for high efficiency phosphorescence OLED. A high efficiency with external quantum efficiency of 20.7% in a green phosphorescent OLED is obtained through minimizing charge trapping in the host guest system and controlling ideal doping concentration in the emitting layer. Our suggested approach ways are very useful for many practical OLED applications.
