摘要

以典型蓝色发光材料-联苯乙烯衍生物(4

4'-bis(2

2'-diphenylvinyl)- 1

1'-biphenyl

DPVBi)为发光层

采用MoO

为阳极缓冲层制备了结构简单的非掺杂型蓝色有机电致发光器件。在电流密度为20 mA/cm

、 MoO

缓冲层厚度为0.5 nm对器件效率约为无缓冲层器件效率的18倍

为通常酞菁铜(Copper phthalocyanine

CuPc)缓冲层器件效率的1.2倍。器件启亮电压为3.3 V

最高外量子效率为3.1％

最高亮度达到16 000 cd/m

器件CIE色坐标(Commission Internationale de l'Eclairage co-ordinates)为(0.15

0.15)。器件性能的提升归因于MoO

缓冲层的插入在阳极/有机层间形成了良好的欧姆接触。
