摘    要:在乙醇溶液中合成了掺杂镧和钆的铽-聚N-乙烯基乙酰胺(PNVA)的掺杂稀土配合物, 并通过红外光谱、紫外光谱、 XPS光电子能谱和荧光光谱研究了该配合物的光谱性质. 结果表明: 掺杂稀土配合物中的稀土离子都与高分子配体PNVA产生配位作用. 配合物的最佳激发波长为303 nm;在此波长激发下, 配合物发出较强铽的特征荧光, 说明非荧光稀土离子(La3 和Gd3 )对Tb3 离子的发光有显著的增强作用, 而对Tb3 的发射峰位影响不大.

关 键 词:稀土  配合物  荧光光谱

Abstract:Terbium-lanthanum(or gadolinium)-poly(N-vinylacetamide) complexes were synthesized and characterized by UV-Vis absorption spectroscopy,FTIR,XPS and fluorescence spectroscopy.The results of UV-Vis,FTIR and XPS suggested that(terbium) and lanthanum(or gadolinium) ions were bonded to amide group of PNVA polymer.Fluorescence experiment indicated that the characteristic emission intensity of terbium ion was greatly increased and possibly sensitized by lanthanum ion(or gadolinium).Moreover,the wavelengths of terbium characteristic emissions were changed slightly.Also the characteristic emission(intensity) of terbium ion doped with lanthanum ion was better than that with gadolinium ion.
Keywords:Rare earth  Complexes  Fluorescence spectroscopy
