英文摘要	文报道了乙酰水杨酸为第一配体，邻菲罗啉为第二配体的铽配合物这种新型电致发光材料，并通过引入导电高分子材料PVK来改善配合物的成膜性和导电性，使其可应用于电致发光器件的发光层。我们制备了单层电致发光器件ITO／PVK：Tb(asprin)3phen／Al，并对其电致发光性能进行了研究。结果表明该配合物具有很好的光致发光性能和电致发光性能。通过测量材料的激发谱和发射谱，我们初步探讨了器件的电致发光机理，认为是PVK及Tb(asprin)3phen激发态的载流子被Tb3＋俘获并与符号相反的载流子在Tb3＋中心上复合，发出Tb3＋的特征发光。; Pure Green and narrow bandwidth emission from organic electroluminescent device was presented by using a new rare earth complex Tb(asprin)(3)phen as emissive layer. The structure of the device was ITO/PVK:Tb(asprin)(3)phen/Al, where PVK was used to improve the film-forming ability and conductivity of Tb(asprin)(3)phen. The electroluminescent property of the device was studied. It proved that this new kind of rare earth complex has excellent optoluminescent and electroluminescent properties. The electroluminescent mechanism of the device was proposed by measuring and analyzing the emission and excitation spectra of the emissive layer. The excitation spectrum of Tb(asprin)(3)phen-dispersed PVK film was very similar to that of the PVK. We proposed that the excited carriers of PVK and Tb(asprin)(3)phen were captured by Tb3+ and light was emitted when the electrons and holes recombinated at Tb3+.; 国家自然科学基金; 北方交通大学校科研和教改项目; 国家研究发展基金; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 0; 3; 267-270; 21
