有机/聚合物顶发射发光器件*

有机/聚合物顶发射发光器件可以解决传统底发射发光器件的一系列不足。高性能顶发射发光器件的实现，首先必须优化器件结构，其次对电子注入材料和空穴注入材料提出更高的要求。本文从提高顶发射器件中电子注入和空穴注入方法入手，综述了国内外有机/聚合物顶发射电致发光器件的发展历史，研究现状，最新进展及以后的发展方向。

Top-Emitting Organic/Polymer Light-Emitting Devices

The rapid development of top-emitting organic/polymer light-emitting devices in the past decades has exhibited a promising prospect in commercial application. Top-emitting devices have several technical merits for application in activematrix flat-panel display compared with traditional bottom-emitting devices.The realization of the high-performance top-emitting devices relies on two major prerequisites which are the exploitation of novel electron injection materials or novel hole injection materials,and the optimization of the device structure.Beginning with the improvement of the electrode modification,which has been proved to be an effective way to enhance their performances,recent progress in top-emitting devices is reviewed.Potential applications and scientific problems in this field are also discussed.
