在一些有机电致发光器件中，A u常被用作阳极，研究者希望A u在导电的同时兼具半透明可出光的属性，这要求Au在能导电的同时厚度要尽量薄。因此制备两种金属共同组成电极成为了选择。将半透明Au/Al层插入阳极一侧，制备了结构为 ITO/Al（16 nm）/Au（10 nm）/TPD（30 nm）/AlQ（30 nm）/LiF（0.5 nm）/Al的OLED器件，相对于器件ITO/TPD（30 nm）/AlQ（30 nm）/LiF（0.5 nm）/Al在长波方向出现了光谱窄化现象，通过分析和实验判断该现象是Au薄膜特有的对光的选择透过性造成，而并非微腔效应。阳极一侧加入了Au/Al的器件保持了广视角无角度依赖的优点，同时可以输出滤掉部分红光的纯度更高的发光，发光色纯度得到了改善。

Au was used as anode in some kind of organic electroluminescent devices .Sometimes transparent Au electrodes are re-quired ,which means that the thickness of Au electrode should be as thin as possible .Therefore ,two metals together forming an electrode become a choice .In the present paper ,translucent Au/Al layer was inserted to anode side ,and OLED device with the structure of ITO/Al (16 nm)/Au (10 nm)/TPD (30 nm)/AlQ (30 nm)/LiF(0.5 nm)/Al was prepared .There is a spectral narrowing phenomenon on the device ITO/TPD (30 nm)/AlQ (30 nm)/LiF (0.5 nm)/Al ,and through analysis and experiment it was found that this phenomenon comes from selective permeability to light of Au thin film rather than the microcavity effect . The device maintains wide viewing angle ,without the angular dependence .And the color purity of device with Au thin film is improved .
