摘要

Highly efficient and stabilized white organic light emitting diodes (WOLEDs) are realized for ultrahigh exciton utilization in article number 1700498 by Silu Tao, Qingxiao Tong, and co-workers. The device uses a novel phenanthroimidazole derivative as the blue emitter as well as the host for red emitters to achieve step-wise energy transfer from the blue emitter to green and red emitters. As a consequence, a high external quantum efficiency over 19% with stable spectra is obtained.
