摘要

用真空蒸发沉积方法制备了一种由8-羟基@4铝(发射层)/二胺(空穴输运层)双层有机膜构成的直流薄膜电致发光(EL)器件。获得了发射峰位于520um的绿色EL.EL光谱极相似于8-羟基喹啉铝粉末的光致发光(PL)光谱。发现当首次对该器件结构施加正向偏压激发电致发光时

出现一个形成过程。实验发现与电致发光形成过程相对应的转变电压可能同有机薄膜的品质及电极蒸发条件有关。

Abstract

Emission spectra and current-voltage characteristics of electroluminescent EL films utilizing 8-hydroxyquinoline aluminum(Alq3) and diamine were measured.Emission spectrum of double-layer EL film made of Alq3 and diamine is similar with that of single layer EL film of Alq3.A forming process appeared in the course of driving EL cell

the transfer-voltage of the process probably is relevant with deposition quality of eletrode and evaporation condition of EL films
