在77K测定了晶粉状Eu(Ⅲ)-TTA-碱三元配合物的精细荧光光谱。并应用群论方法及跃迁选律结合实验测得荧光光谱中各f-f能级跃迁对应的谱峰的分裂数目,推断出各三元配合物中Eu(Ⅲ)所处近邻的点对称性。
The fine fluorescence spectra of crystalline Eu (III) -TTA-base ternary complexes were measured at 77K. The group symmetry of the nearest neighbor of Eu (Ⅲ) in each ternary complex was deduced by using the method of group theory and the transitional law of combination to determine the number of splitting of the peak corresponding to each f-f level transition in the fluorescence spectrum.
