摘要
对稀土元素铕、铽、镝的氯化物与咪唑二元配合物 ,与丙氨酸、咪唑三元配合物 ,乙酰甘氨酸铕、镧、钕、铕与苯并咪唑配合物以及它们的配体 ,以可见光为激发光进行了荧光光谱测量 ,比较了不同稀土元素的荧光特性 ,分析了不同配体对稀土离子荧光特性的影响 ,讨论了稀土离子在配合物中的发光机制 ,同时还观察分析了升频荧光现象 .
The fluorescence spectra of rare earth complex were measurement with visible excited light.The rare earth complex are bifunctional complex of rare earth chlorides of Eu,Tb,Dy with imidazole,ternary complex of rare earth chlorides of Eu,Tb,Dy with alanine and imidazole,Eu with acetylgcine,bifunctional of La,Nd,Eu with Benzimidazole and their ligands.Their spectral properties were compared.The affects of different ligand to fluorescence properties of rare earth ions were investigated.The luminescent fluorescence was observed and studied.
