摘要

提出一种用于有机电致发光器件(OLED)的双面对称矩形金属光栅电极

采用时域有限差分方法(FDTD)模拟研究了OLED中表面等离子体激元的激发和耦合传输的物理规律和物理机制

详细计算和分析了该光栅结构的周期、槽宽、光栅高度、槽底厚度、入射光的入射角与电极透射效率的关系

并由此优化了结构的几何参数

使金属电极的光导出效率相对于通常的金属银层电极增强了1.77倍

为基于表面等离子体激元的高效光导出器件的优化设计提供了理论依据。

Abstract

A kind of two-sided symmetrical rectangular metal gratings used in OLED structures as electrode is proposed. The exciting

coupling and transmiting of Surface plasmon polaritons are similated and analyzed with Finite-difference Time-domain(FDTD) method. Particularly the relation of light-output efficiency and periods

the groove width

the grating height

the thickness of the metal film

the angel of incident light are analyzed

respectively. By optimizing this gratings parameters

its transmissivity can be 1.77 times of traditional metal electrode.Providing technical and theoretic support to the desigh of high efficiency light out-coupling devices based on surface plasmon polaritons.
