摘要

在具有电致发光(EL)的有机整合染料8-羟基喹啉铝(Alq3)中接以染料罗丹明6G(R6G)

用真空热蒸发的方法制备器件

获得了峰值波长575nm的黄色直流薄膜电致发光

从而通过掺杂改变了发光颜色.并在Alq3发光层不同区域插入一掺杂薄层(Alq3:R6G)

利用其发光波长与未掺杂部分(Alq3)的不同

以此作为“探测层”

通过对器件光谱及电学特性的测量与分析

探讨了有关发光区域

发光机理

界面对发光影响等基本问题.

Abstract

The DC drived EL devices have been prepaired by means of conventional vacuum vapour deposition. The emitting material of these devices is Rhodamine (R6G) doped organic chelate dye 8-hydroxyquinoline aluminium (Alq3). The wavelength of devices changed from Alq3's 523urn to 575urn. Moreover

a doped Alq3 thin film whose emission colour is different from undoped Alq3 emitting layer was used as a "sensing layer".The spectra and

I-V

character were measured and the emission zone

interface effect

energy transfer mechanism and other fundamental problen of luninescence were discussed.
