摘　　要：氨基酸是生命系统中蛋白质的基本结构单位 .本文通过共沉淀法合成了色氨酸与稀土元素Eu(Ⅲ )的固体配合物 ,并对其进行了光谱及波谱研究 ,确定了配合物的配位机理及配位点 .Amino acids are the primary units of proteins. In this paper, solid complex of tryptophan with rare earth element Eu(Ⅲ) was prepared by coprecipitation method. The complex was characterized by fluorescence, IR, Thermogram, scanning electron microscope. Furthermore, the complexing mechanism and complexing site were studied by \{\}\+1H NMR and \{\}\+\{13\}C NMR.\;
