摘　　要：对在水中合成的稀土元素(Eu、T b、D y)与L-脯氨酸(L-P ro)、甘氨酸(G ly)、L-丙氨酸(L-A la)四元固态配合物的荧光光谱进行了研究。结果表明:铕、铽配合物的荧光强度均较其相应的盐高(铕高出4.5倍,铽高出9倍);四元配合物的荧光强度较三元配合物有不同程度的提高;四元配合物中,铽的荧光强度较铕的荧光强度高出近11倍。同时对上述实验结果进行了解释。The solid complexes of Eu^3＋ ,Tb^3＋ and Dy^3＋ with L -Proline,L-Alanyl and Glycine were synthesized in water solution. The fluorescence intensities of the quaternary complex of Eu^3＋ increased by 4.5 times and Tb^3＋ increased by 9 times as compared with those of the rare earth chloride. The fluorescence intensities of terbium is higher 11 times than that of europiurn. All above phenomena were also discussed.
