利用铜酞菁薄膜充当缓冲层 ,研究了缓冲层对有机电致发光器件性能的影响 ,研究结果表明含有铜酞菁缓冲层的器件性能明显优于不含有缓冲层的器件 ,加入铜酞菁缓冲层后器件发光稳定性也得到了改善。本文对相关机理进行了探讨 ,分析认为 ,铜酞菁本身的热稳定性和它能够降低空穴注入势垒的性质是提高器件性能的主要原因 The effect of buffer layer on the performance of organic electroluminescent devices was studied by using copper phthalocyanine film as a buffer layer. The results show that the performance of devices containing copper phthalocyanine buffer layer is obviously better than those without buffer layer. Copper phthalocyanine buffer Luminescence stability of the device after the layer has also been improved. In this paper, the relevant mechanism is discussed, the analysis shows that the thermal stability of copper phthalocyanine itself and its ability to reduce the hole injection barrier is the main reason to improve device performance
