Solution-Processed White Phosphorescent Tandem Organic Light-Emitting Devices

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.

Summary: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.
