摘要

将负折射率介质层(NRIDL)引入到微腔有机电致发光器件(MOLEDs)中

设计了新型的微腔器件。利用传输矩阵法对此器件的反射率大小、器件厚度对发射峰的影响以及电致发光(EL)光谱性质进行了分析和讨论。结果表明:与普通微腔器件相比

新型微腔器件的谱线宽度显著窄化

峰值强度明显增强

并且受腔体长度的影响较小。这些结果为进一步提高微腔器件的发光色纯度、薄化器件厚度提供了新方法。

Abstract

The negative refractive index dielectric (NRID) was introduced into the microcavity organic light-emitting device(MOLEDs). The new microcavity containing negative refractive index dielectric layer(NRIDL) was exhibited. Firstly

the transmission matrix model of the negative refractive index dielectric was presented. Based on the transfer matrix method

the reflectance spectrum

the dependence of EL spectra on cavity thickness were analyzed and discussed. The results showed that the line widths of the spectra of the new MOLED are narrower and all the peaks are enhanced

comparing to the electroluminescence spectra of non-NRIDL device. And then

the luminescence characteristics and EL spectra of the microcavity OLEDs are theoretically studied. The cavity thickness has few effect on the EL spectrum. All the results show that it is a new way to enhance device efficiency

color purity and thinned the thickness of the MOLEDs.
