| 摘 要： | 磷光材料由于可以利用电致激发所形成的单重态和三重态激子，因而可以得到接近100%的内量子效率。文章对常温下基于磷光材料Ir(ppy)3及Ir(piq)3掺杂PVK薄膜为发光层的器件的光学和电学特性进行了研究。光致发光的结果显示相同掺杂质量比下由PVK到Ir(piq)3的能量传递比到Ir(ppy)3更加困难。通过研究两种掺杂体系不同质量比的电致发光特性，可以认为这两种磷光器件的发光主要来自于磷光客体分子直接俘获载流子发光而非主体的能量传递。Ir(piq)3掺杂体系对掺杂比例的依赖更为明显，从能级结构分析，认为是由于Ir(piq)3的更低的HOMO及高的LUMO能级，而比Ir(ppy)3具有更好的载流子俘获和传输特性。
