我们研究了以聚甲基苯基硅烷（PMPS）为空穴传输材料的聚硅烷基多层电致发光（EL）器件的光学和电学性质，以阐明这些器件中的EL发射机制。我们制作的电致发光器件具有两个或三个功能有机层。这些层由PMPS层以及3-（2 '-苯并噻唑基）-7-二乙基氨基香豆素（香豆素6）掺杂的聚苯乙烯（PS）层和/或三-（8-羟基喹啉）铝（Alq 3）层组成。将铟锡氧化物涂覆的玻璃和Al电极分别用作孔和电子注入电极。结合器件的基本特性、光激发荧光光谱和衰减曲线以及能带图的分析，我们得出结论：三层器件中载流子的复合和电致发光都发生在Coumarin 6：PS和蒸发的Alq 3层中。
We have investigated the optical and electrical properties of polysilane‐based multilayer electroluminescent (EL) devices, utilizing poly(methylphenylsilane) (PMPS) as the hole transporting material, in order to elucidate the mechanism of EL emission in these devices. The EL devices which we fabricated have two or three functional organic layers. These layers are composed of a PMPS layer as well as a 3‐(2’‐Benzothiazolyl)‐7‐diethylaminocoumarin (Coumarin 6) doped polystyrene (PS) layer and/or a tris‐(8‐hydroxyquinoline) aluminum (Alq3) layer. An indium‐tin‐oxide‐coated glass and an Al electrode were used as the hole and the electron injecting electrode, respectively. On the basis of a combined analysis of the basic characteristics of these devices, photoexcited fluorescence spectra and decay curves as well as the band diagram of these devices, we concluded that the recombination of charge carriers and the EL emission in the three‐layer device occur both in the Coumarin 6:PS and the evaporated Alq3 layers.
