摘要

采用双层银膜夹入有机物薄膜形成的复合阳极结构

结合具有高透射率的银锗银复合阴极制备了单向发射的半透明红光有机电致发光器件。由于共振隧穿效应使得复合电极对不同波段可见光具有选择性透过的特点

制备的器件表现出单向发射特征。在相同偏压下

器件在非发射方向的亮度始终在发射方向的3%以下。器件在9.5 V电压下达到最大亮度

在发射方向和非发射方向上的亮度分别为15 550 cd/m

和387 cd/m

。在7.5 V电压下

器件达到其最高电流效率7.01 cd/A。在该偏压下

其发射与非发射方向亮度分别为4 968 cd/m

和151.7 cd/m

。器件光谱的稳定性很好

随着电压的增加

没有发生明显的变化。此外

随着视角的变化

器件的光谱也无明显的角度特性。当视角从0增加到60时

其色坐标仅改变(-0.002

0.001)

这是由于银锗银复合阴极具有较高的透射率和低的反射率。

Abstract

One-direction-emission red transparent organic light-emitting device employing Ag/organic/Ag anode and Ag/Ge/Ag cathode was fabricated. The photonic tunneling effect existing in the multilayer electrode results in the alternative transmission property of the electrode

and the device employing the multilayer electrode exhibits one-direction-emission property. At the same bias voltage

the brightness of the non-emission side is less than 3% of that of the emission side. The brightness from emission side and non-emission side are 15 550 and 387 cd/m

at 9.5 V

respectively. The devices attain its maximum current efficiency of 7.01 cd/A at 7.5 V

and the brightness from emission side and non-emission side are 4 968 and 151.7 cd/m

respectively. Besides

the device also shows an excellently angle-stable characteristic. As the viewing angle increases from 0 to 60

the chromaticity coordinate only shift (-0.002

0.001)

which should be attributed to the relatively high transmission and low reflectivity of the Ag/Ge/Ag cathode.
