Abstract

High efficiency phosphorescent white organic light emitting diodes (PHWOLEDs) were fabricated by controlling the charge transport properties of host materials. Blue/red/blue stack structure was used and the use of hole transport type host material in red emitting layer was effective to improve the quantum efficiency of PHWOLEDs. High quantum efficiency of 12.2% was obtained in PHWOLEDs.
