【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。更多还原

【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.更多还原
