摘要

有机电致发光器件的发光颜色与色纯度在很大程度上受材料本身的限制

而通过光学微腔效应可以从器件结构上的改变来调节色纯度。本文介绍了一种通过调节有机层厚度

从而获得高纯度单色发光器件的方法。利用这种方法制作了有机顶发射蓝光器件

器件结构为Ag/m-MTDATA/NPB/DPVBi/Alq

/LiF/Al/Ag)。通过调节有机层的厚度

获得了高色纯度的发光器件

正向出射的蓝光色坐标达到了(0.14

0.07)。

Abstract

The color purity of organic light-emitting devices is restricted mostly by the intrinsic character of emitting material

but optical cavity can improve the color purity via changing the structure of devices. In this paper

we demonstrated that highly saturated homo-chromaticity light can be obtained by adjusting the thickness of organic layers. Organic top-emitting electroluminescent devices were fabricated in this method

the structure of the device was Ag/m-MTDATA/NPB/DPVBi/Alq

/(LiF/Al/Ag)

and direct blue emission with Commission Internationale de LEclairage chromaticity coordinates of (0.14

0.07) was obtained.
