Abstract

High quantum efficiency above 18% and extended lifetime three times longer than that of phosphorescent organic light-emitting diodes (OLEDs) are demonstrated in blue thermally activated delayed fluorescent OLEDs.

Keywords: blue device; carbazole; delayed fluorescence; efficiency; lifetime; triazine.
