| 英文摘要 | An efficient phosphorescent white organic light emitting-diode with a red-green-blue 3tri-emitting-layer structure is reported. The host of the red dopant possesses a lower triplet-energy than the green dye. An interlayer step-wise triplet transfer via blue dye -> green dye -> red host -> red dye is achieved. This mechanism allows an efficient triplet harvesting by the three dopants, thus maintaining a balanced white light and reducing energy loss. Moreover, the color stability of the device is improved significantly. The white device not only achieves a peak external quantum efficiency of 21.1 +/- 0.8% and power efficiency of 37.5 +/- 1.4 lm/W but shows no color shift over a wide range of voltages.
