摘要

本文采用的有机发光材料为8-羟基喹啉铝(8-Alq)

结构为ITO/8-Alq/Al夹心式单层EL结构

制备三种不同厚度:300(Å)

600(Å)

1500(Å)的有机薄膜EL样品.对比和分析它们的

I-V

和

B-I

特性曲线

证实发光层厚度对有机薄膜EL样品的亮度产生显著影响

并在稳恒直流电压激发下

探讨了电子和空穴载流子在发光薄膜中的输运

据此分析了产生上述影响的主要原因.

Abstract

In this paper

three organic thin film electroluminescence (OTFEL) cells with different thickness of luminescent layer:300Å

600Å

1500Å

were prepared. The OTFEL cells were the structure of single layer

and the 8-hydroxyquinoline aluminum was used as a luminescent layer. Comparing and analysising their properties of

I-V

and

B-I

it is conformed that the thickness of luminescent layer drastically influences the brightness of OTFEL cells. The cause were discussed by transport processes of electrons and holes in luminescent layer under DC current.
