摘要：
Solution-processed phosphorescent tandem organic light-emitting devices (OLEDs) exhibit extremely high efficiencies (94 cd A-1) and 26% external quantum efficiency (EQE) at 5000 cd m-2 for green phosphorescent devices and 69 cd A-1 and 28% EQE at 5000 cd m-2 for white phosphorescent devices. Development of these highly efficient solution-processed tandem-OLEDs with inverted device structure paves the way to printable, low-cost, and large-area white lighting. © 2015 WILEY-VCH Verlag GmbH & Co.
