摘要

研究了耦合微腔结构的有机发光器件的光学和电致发光性能。通过将被动腔作为底部反射镜的方法

简化了耦合微腔的光学和发光性能的模拟

所得到的结果与实验符合得较好。在相同电流密度下与同样结构的普通OLED相比

耦合腔OLED的光谱强度在502 nm处增强了3.6倍

在550 nm处增强了5.6倍

光谱积分强度增加了0.5倍。普通OLED的最大电流效率和亮度是4.2 cd/A 和13 600 cd/m

。而耦合腔OLED则为7.0 cd/A 和 22 660 cd/m

。这种结构的器件出射光更集中于腔轴方向

有利于设计开发较高效率的有机激光器件。

Abstract

The optical and electroluminescent(EL) properties of organic light emitting devices(OLED) with a coupled microcavity(CMC) structure were investigated. CMC is a kind of complicated microcavity. The modeled optical and luminescent properties of the CMC is simplified by treating the passive cavity as a bottom mirror

and consistent with the measured results. The EL spectral radiance of the CMC in the normal direction was enhanced by a factor of 3.6 at peak of 502 nm

5.6 at peak of 550 nm

and 0.5 at the whole spectrum region comparing with the normal OLED driving at the same current density. The highest current efficiency and luminance of 7.0 cd/A and 22 660 cd/m

for the CMC were obtained in the normal direction

comparing with those of 4.2 cd/A and 13 600 cd/m

for the noncavity OLED.
