摘要：
Efficient WOLEDs employing phosphorescent sensitization are investigated. Devices with a single phosphor-sensitized emitting layer can give colors close to (0.33, 0.33) and efficiencies up to (10%, 23 cd/A, 13.4 lm/W). Devices with a sensitized emitting layer and a phosphorescent layer further enhance the efficiencies up to (12.1%, 35.3 cd/A, 23.9 lm/W). In all phosphor-sensitized WOLEDs, the efficiency roll-off at higher currents is much reduced.
