英文摘要by using a single host for both blue and orange phosphorescent dopants, a simple and efficient white organic light emitting-diode is reported. the dual-emissive-layer white device achieves a peak external quantum efficiency of 16.9 +/- 0.9% and power efficiency of 44.1 +/- 2.3 lm/w without out-coupling enhancement. analysis of the device working mechanism determines that the blue dopant molecules can form a bridge to facilitate electron transport into the adjacent orange emitting-layer. the orange emission originates from both the direct electron trapping by the orange dopant and incomplete blue-orange energy transfer mechanisms. the origin of the voltage-dependent color shift of the device is quantitatively determined according to the working mechanism. possible solution to reducing the color-shift is also provided based on the calculation and analytical results.
