Tb3+与氨基酸混配型配合物的合成与表征
Synthesis and Characterization of the Mixed Ligand Complexes of Tb 3+ with Amino acids
【摘要】 在乙醇溶液中合成了ＴｂＣｌ３，Ｔｂ（ＣｌＯ４）３与Ｌ－脯氨酸、甘氨酸形成的二种三元固态配合物Ｔｂ（Ｐｒｏ）０．５（Ｇｌｙ）２．５Ｃｌ３·５Ｈ２Ｏ和Ｔｂ（Ｐｒｏ）０．５（Ｇｌｙ）２．５（ＣｌＯ４）３，并通过摩尔电导、红外光谱、热分析及粉晶荧光光谱等进行了表征．荧光光谱表明，Ｔｂ（Ｐｒｏ）０．５（Ｇｌｙ）２．５Ｃｌ３·５Ｈ２Ｏ配合物中Ｔｂ３＋的５Ｄ４→７Ｆ５跃迁谱带强度较Ｔｂ（Ｐｒｏ）０．５（Ｇｌｙ）２．５（ＣｌＯ４）３中对应谱带强度高２８倍
【Abstract】 Two solid ternary complexes of terbium chloride,terbium perchlorate with L proline and glycine with formula Tb(Pro) 0.5 (Gly) 2.5 Cl 3·5H 2O,Tb(Pro) 0.5 (Gly) 2.5 (ClO 4) 3 have been synthesized in alcohol solution and characterized by molar conductance,IR spectra,thermal analysis and fluorescence spectra.In the fluorescent experiments it was found that fluorescence emission intensity for Tb 3+ ion( 5D 4→ 7F 5) in Tb(Pro) 0.5 (Gly) 2.5 Cl 3·5H 2O is 28 times more than that in Tb(Pro) 0.5 (Gly) 2.5 (ClO 4) 3.
