本文主要研究了有机半导体微腔发光增强性质的问题。微腔的发光层由空穴转移型对次苯基聚合物和电子转移型的染料掺杂8羟基喹啉铝异质结构组成。通过调节Al和ITO电极之间有机聚合物层厚度达到微腔效应。研究结果表明这种结构的微腔极大地增强了电致发光效率。

The microcavity efficiently enhancement of organic electroluminescent devices was investigated, the devices is consisted of the hole transporter ladder-type poly (p-phenylene) and the electron transporter 8-hydroxyquinoline aluminum with dye pyrromethene-doping. The microcavity effect could be achieved by adjusting organic layer thickness between Al and ITO electrode. The results obtained showed that the microcavity electroluminescence efficiency was greatly enhanced.
