摘要
研究互掺过渡层对有机电致发光器件性能的影响 .在有机发光二极管 (OL ED)的电子传输层 (ETL)与空穴传输层 (HTL)、空穴传输层与空穴注入缓冲层之间 ,加入由这两层材料组成的浓度渐变互掺过渡层 .它消除有机层间的界面 ,减少有机层间的缺陷 ,且与没有过渡层的器件相比 。
A study is devoted to the effect of a mutual doped transitional layer on the performance of organic electroluminescent device. The conventional organic light emitting diode consists of electron transport layer(ETL) and hole transport layer(HTL).The authors suggest to add a mutual doped transitional layer which is made up by the material of ETL and HTL with a concentration of gradually changing. By adding this mutual doped transitional layer to the interspace of ETL and HTL and to the interspace of HTL and a buffuer layer of hole injection, the interface of ETL and HTL will be eliminated and the defect of them will be reduced and thus the performance of the device will be evidently improved as compared with that of conventional device.
