| 摘 要： | 有机发光二极管(OLED)在通信、信息、显示和照明等领域均显现出巨大的商业应用前景,十几年来一直是光电信息领域的研究热点之一.但是,OLED的外量子效率远低于内量子效率,极大程度地制约了其发展和应用.本文主要介绍了多种有效提高器件效率的光取出技术,对微透镜、光子晶体结构、纳米图案和纳米多孔膜以及微腔技术等多种OLED修饰方法进行了回顾和讨论.在此基础上,对一些光取出技术的研究做了展望.

| Abstract: | Organic light-emitting device (OLED) technology shows tremendous commercial applications in communication, information, display, and lighting. It has been one of the most attractive projects in optoelectronic information field over the last decade. However, the internal efficiency is quite different from the external efficiency, and to some extent, a low external efficiency restrictes the development and application of OLEDs. The light out-coupling has been improved by a number of different techniques through the modification of device architecture. In this paper we present various light out-coupling techniques that have been implemented to enhance the external efficiency of OLEDs. Various OLED device modification techniques, e.g., micro-lens array, photonic crystal structure, nano-patterned and nanoporous films, and microcavity technique, have been reviewed and discussed. Finally, some perspectives on light out-coupling techniques are proposed. |
