聚合物白光发光二极管的研究进展

Development of Study on White Polymer Light-Emitting Diodes

针对聚合物白光发光二极管(WPLEDs)在显示和照明领域广阔的应用前景,从器件结构和相关材料方面进行了讨论。从结构上将白光器件分为单发光层器件和多发光层器件;从发光材料的性质上将白光器件分为荧光器件、磷光器件和单一高分子白光器件。通过探讨各种器件的优势和不足,提出了各种器件的发展方向,并对WPLEDs面临的机遇和挑战做出了评述。

White polymer light-emitting diodes （WPLEDs）, which are seen as the next generation solid-state lighting source, have been developing greatly in the past two decades due to their potential applications in large-area flat panel displays and lighting field. In this paper, the domestic research progress of WPLEDs is introduced mainly from the device structure and the character of luminescent materials. Thc WPLEDs are classified into single white light-emitting devices and multi-layer light-emitting layer devices from the structure of the devices. Furthermore, from the character of the material, The WPLEDs are classified into fluorescent devices, phosphorescent devices, and single white emitting polymer devices. The strengths and weaknesses of WPLEDs are investigated in detail. Moreover, the commentary of opportunities and challenges of WPLEDs is also talked over in this paper.
