Abstract

A very-high color rendering index white organic light-emitting diode (WOLED) based on a simple structure was successfully fabricated. The optimized device exhibits a maximum total efficiency of 13.1 and 5.4 lm/W at 1,000 cd/m. A peak color rendering index of 90 and a relatively stable color during a wide range of luminance were obtained. In addition, it was demonstrated that the 4,4',4″-tri(9-carbazoyl) triphenylamine host influenced strongly the performance of this WOLED. These results may be beneficial to the design of both material and device architecture for high-performance WOLED.

摘要

成功制备了一种基于简单结构的高显色指数白色有机发光二极管（WOLED）。优化后的器件在1000 cd/m²时的最大总效率为13.1和5.4 lm/W。获得了90的峰值显色指数以及在宽亮度范围内相对稳定的颜色。此外，结果表明4,4',4″-三（9-咔唑基）三苯胺主体对该WOLED的性能有很大影响。这些结果可能有利于高性能WOLED的材料和器件结构设计。
