Abstract

We have controlled doping profile and layered structure of electrophosphorescent device system for enhanced efficiency and lifetime. Power efficiency was improved dramatically only by the doping profile change at emission layer. Proposed mechanism was further confirmed by use of different hole blockers. We explained underlying physical mechanism of device by the charge trapping and energy level alignment.
