摘要

通过在Ag层中引入一层Ge薄膜

获得了具有低反射率和高反射相移的Ag/Ge/Ag复合阳极

并制备了基于该阳极的蓝光顶发射有机电致发光器件.阳极高的反射相移使得器件在有机层厚度为100 nm时获得了顶发射蓝光发射

且阳极较低的反射率减弱了器件内的微腔效应

使得其电致发光光谱在不同视角下具有良好的稳定性.当Ge的厚度为20 nm时

器件性能表现最为优良

最高亮度和最大电流效率分别可达3 612 cd/m

和5.4 cd/A

且色坐标在视角从0变化到60时仅移动了(0.007

0.006).

Abstract

The low-reflectivity Ag/Ge/Ag anode obtained by inserting germanium into sliver is used to fabricate the blue top-emitting organic light-emitting devices. Top-emitting blue emission can be achieved in the device with 100 nm organic layers due to the high phase change on reflection of the anode. The low reflectivity of the anode is helpful to weaken the microcavity existing in the devices

resulting in the angle-stable blue emission. When Ge thickness is 20 nm

the performance of the device is the best. The maximum luminance and current efficiency of the device are 3 612 cd/m

and 5.4 cd/A

respectively

and its chromaticity coordinates only shift (0.007

0.006) with the view angle from 0 to 60.
