摘要

制备了基于双母体结构的高效率蓝色磷光有机电致发光器件。通过与采用单母体结构和双发光层结构的器件性能进行对比'发现双母体结构的应用对蓝光器件的性能起到了明显的提升作用。双母体蓝光器件的最大效率为14.9 cd/A（13.3 lm/W）'最大亮度达到10 440 cd/m

'其开启电压仅为2.7 V。蓝光器件同时展示出低的效率滚降特性'在100~5 000 cd/m

范围内'器件的效率滚降仅为35.3%。在3~8 V的电压变化内'器件的色坐标一直位于蓝光区域。

Abstract

Highly efficient blue organic light-emitting diodes based on mixed host structure were successfully fabricated. Two blue devices with structure of single host and double emission layers were fabricated as comparison. It is showed that the employment of mixed host structure can enhance the performance of blue device obviously. The mixed host blue OLED with low turn on voltage of only 2.7 V shows maximum efficiencies of 14.9 cd/A (13.3 lm/W) and maximum luminance of 10 440 cd/m

. Moreover

this blue device also shows very low efficiency roll-off. The current efficiency only drops 35.3% from the luminance of 100 cd/m

to 5 000 cd/m
