中文摘要：
制作了一种以Al为金属反射膜和金属半透膜的微腔有机电致发光器件（OLED）。器件结构是：Al/MoO3/NPB/ADN∶TBPe∶DCJTB/Alq3/LiF/Al。设计了五种厚度的金属Al阳极半透膜器件,Al半透膜的厚度依次为：12nm,13nm,14nm,15nm,16nm。通过调节阳极Al半透膜的厚度,改变微腔的光学长度,研究微腔效应对器件性能的影响。利用Al半透膜阳极厚度的变化,调整微腔器件的光学长度,发光效率和色纯度也随之变化。当Al半透膜为12nm时,器件在11V获得最高亮度3 381cd/m^2,最高效率为2.01cd/A,色坐标为（0.33,0.39）。实验表明,合理利用微腔效应,可提高以Al为阳极器件的色纯度,并保持一定的发光效率。
英文摘要：
A microcavity organic light-emitting diode（OLED） device with the structure of Al/ MoO3/ NPB/ ADN∶TBPe∶DCJTB/ Alq3/ LiF/ Al is fabricated using Al as the metal reflective film and metal semipermeable membrane.Five kinds of devices with Al anode semipermeable membrane designed for different film thicknesses as： 12 nm,13 nm,14 nm,15 nm,16 nm,and the effects on the performance of OLED micro-cavity are researched.The results show that both the luminous efficiency and color purity change with the optical length of the micro-cavity.When the thickness of Al semipermeable membrane is 12 nm,the device can obtain the maximum brightness of 3 381 cd/m^2,highest efficiency of 2.01 CD/A,and color coordinates of（0.33,0.39） at 11 V.Therefore,using microcavity effect reasonable can improve the color purity of the device and maintain a certain luminous efficiency.
