摘要
应用沉淀法合成了若干稀土离子（RE=Y、La、Pr、Nd、Sm、Gd、Tb、Dy）与酒石酸（H2L）的配合物，通过X射线粉末衍射、红外光谱等对配合物的结构进行了表征，测定了该系列配合物的荧光性能．实验结果表明，该类配合物的结构为RE2L3.8H2O（R＝Y、La、Pr、Nd、Sm、Gd、Tb、Dy），且Tb2L3材料具有较好的发光性能，
The complexes of na earths (RE = Y, In, Pr, Nd, Sm, Cd,Tb, Dy) with tartaric acid having the compositions RE2L3. 8H2O were synthesized by the soution reachon method. The new complexes were chaxacterized by x - ray diffraction and IR spectra. The fluorescence spectra of RE2L3 have been investigated. The results showed that Tb2L3 was better material having fluorescence properties.
