摘　　要：为了获得更好的发光器件,将有机材料与无机材料制成复合体,取长补短,使其在平板显示技术中具有极大的应用前景。本文在简述有机与无机电致发光原理的基础上,介绍了有机-无机复合器件的研究进展,重点阐述在具有不同结构的有机-无机异质结器件中无机材料所起的作用。通过对无机界面修饰层修饰电极、基于Ⅱ-Ⅵ族半导体材料有机无机复合电致发光等方面的综合探讨,总结出有机-无机复合器件的优势:能得到更好的I-V特性曲线和更高的发光效率,对器件内部场强起调节作用并且改善两种载流子的平衡注入,为今后在制作有机-无机复合器件方面做更深入的研究提供参考。At present, OLEDs （ organic light emitting devices） have acquired brilliant achievement in the research into photo-electricity field. Based on the OLEDs , organic lasers and organic thin-film transistor developed by scientists reseaching in recent years can be widely used in integrated optics, optical communications. But organic photoelectric materials face a series of issues, such as low electron injection efficiency, poor stability and short life of the device. In order to obtain better light-emitting devices, organic materials and inorganic materials complex in the use of each other＇s strengths to make up for the weaknesses of one side, they have great application prospects in the flat panel display technology. The country scientists focus on different structures of organic-inorganic beterojunction devices after researching currently. After briefly introducing the organic and non-light-emitting principle, this paper introduces research progresses of organic-inorganic composite device, especiall setting forth the inorganic materials in the role of the organic and inorganic compound device, and finally deals with the future prospects for development.
