| 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/m2。而耦合腔OLED则为7.0 cd/A 和 22 660 cd/m2。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 spect... |
