摘　　要：合成了铈-对甲基苯甲酸-2,2-联吡啶三元固体配合物。利用元素分析、红外光谱(FT-IR)、紫外-可见光谱(UV-Vis)、热重分析(TGA)和荧光光谱等手段研究了配合物的结构和性质。结果表明配合物的组成为[Ce(PTA)0.75(BPY)].3.8H2O,荧光光谱表明配合物都具有较好的荧光特性,且发射谱线很窄,主发射峰为Ce3+的5D4→7F6跃迁,具有很高的荧光强度,研究表明合成的新型稀土配合物是一种良好的发光材料。The novel ternary solid complex of rare earth with p-toluic acid and 2,2-bipyridine was syn- thesized. The chemical structure and properties of the complex were characterized by using the element analysis, FT-IR, UV-Vis spectroscopy, thermal gravimetric analysis （TGA） and fluorescence spectros-copy. Its composition was determined to be [Ce（PTA）0.75 （BPY）]3.8H2O. The fluorescence spec-trum suggested that the innovative complex containing rare-earth ions, which had special fluorescence properties with a strong characteristic emissions appeared due to the ^5D4→^7F6 transition of the central Ce^3＋ ions,is a kind of outstanding photoluminescence materials.
