摘要

采用一种宽谱带绿光发光材料

通过两个颜色互补的谐振模式结构设计实现了白光发射的微腔OLED。与普通结构的OLED相比

器件的电致发光效率提高了0.7倍。优化后的白光微腔OLED的色坐标为(0.34

0.33)

且颜色不随工作电压变化。进一步改善显色指数性能则需要构建多个模式的微腔结构。

Abstract

A white light microcavity organic light-emitting device (WOLED) was fabricated and characterized. Design method of WOLED has been studied.This microcavity has two color matched cavity modes structure and a wide band green organic luminous material. Comparing with the normal structural OLED

EL efficiency of microcavity WOLED was improved by 0.7 times. Optimized microcavity structure can lead to a color coordinator of (0.34

0.33). The CIE of microcavity OLED was stable at different volatge. Further study should focus on multi mode cavity structure for optimizing color rendering index.
