摘　　要：在乙醇溶液中合成了三种稀土与Ｌ－酪氨酸、甘氨酸的三元固态配合物ＲＥ（Ｔｙｒ）１．５（Ｇｌｙ）４（ＣｌＯ４）３（ＲＥ＝Ｐｒ、Ｅｕ、Ｔｂ）．并通过摩尔电导、红外光谱、热谱和荧光光谱等进行了表征。铽（Ⅲ）配合物的荧光强度（Ｔｂ：５Ｄ４→７Ｆ６、７Ｆ５、７Ｆ４）比铽（Ⅲ）水合高氯酸盐增大了一个数量级．Three solid ternary complexes of rare earths with L tyrosine and glycine with the formula RE(Tyr) 1.5 (Gly) 4(ClO 4) 3 (RE=Pr,Eu,Tb) have been synthsized in alcohol solution and characterized by molar conductance,IR spectra,thermal analysis and fluorescence spectra.The fluorescence intensities of the complex of Tb(Ⅲ) (Tb: 5D 4→ 7F 6, 7F 5, 7F 4) have increased by one order as compared with those of the corresponding perchlorate hydrates.
