【摘要】 介绍了微腔有机发光器件(MOLED)的设计思想、方法和结果。该器件由Alq3作为电子传输层和发光层,TPD作为空穴传输层,ITO作为空穴注入电极,两侧分别分布布喇格反射镜(DBR)和由Al电极形成的金属反射镜。理论设计结果表明,MOLED的峰值光强增强19倍,谱线半宽度从100nm变窄到10nm左右。更多还原

【Abstract】 Microcavity organic light emitting device is designed in this paper. The device consists of electron transporting layer and light emitting layer(Alq3), hole transporting layer(TPD) and hole injection layer(ITO) . There are distributed Bragg Reflector(DBR) and Al metal reflector on two sides of the device. It is proved that spectral full width at halfmaximum of MOLED changes from 100nm to 10nm and the light intensity of peak wavelength is increased by 19 times than that of OLED.更多还原
