合成并采用DPVB作为发光层 ,Al/LiF双层电极作阴极 ,得到了高亮度 (>980 0cd/m2 )、高效率 (1.7lm/W )的蓝色有机电致发光器件 .
DPVB was used as the light-emitting layer and the Al / LiF double-layer electrode was used as the cathode to obtain a blue organic electroluminescent device with high luminance (> 980 0 cd / m2) and high efficiency (1.7 lm / W).
