Progress of White-light Polymer Light-emitting Devices and Materials

白光聚合物电致发光器件具有低能耗、低驱动电压、绿色环保以及可制备柔性屏等诸多优异特性,被业界公认为是21世纪最具潜质和最具发展前景的高技术领域之一。此外,白光聚合物电致发光器件可通过湿法加工技术(如旋涂、丝网印刷、喷墨打印)来制作,因而其制作成本低,在显示和照明领域有着广阔的应用前景,受到人们广泛的关注。从器件和材料两个方面开展论述,简单介绍了白光聚合物电致发光的最新研究进展,并分析了实现白光聚合物电致发光器件商用化所需解决的问题。

White-light polymer light-emitting devices （PLEDs） are recognized as one of the most promising potential high-tech areas in 21st century because of low power consumption, no-pollution and flexible screen. PLEDs can be prepared by wet processing technology （such as spin coating, screen printing, inkjet printing）, so their costs can be reduced in display and lighting applications. Some of representative white electroluminescent polymers and devices are introduced, and the problems needing to be solved before commercialization are summarized.
