合成了稀土Tb -N 苯基邻氨基苯甲酸 -1,10 - 菲咯啉二元、三元配合物。通过元素分析确定二元配合物的组成为TbL3 ·4H2 O ,三元配合物的组成为TbL3 phen·2H2 O(L :N 苯基邻氨基苯甲酸根 ,phen :1,10- 菲咯啉 ) ,讨论了两种配合物的谱学性质。通过荧光光谱测试发现 ,形成的TbL3 ·4H2 O二元配合物的荧光强度明显降低 ,1,10 - 菲咯啉作为第二配体引入后 ,使Tb3 + 的发光强度继续降低 ,这说明了Tb3 + 的发光强度与配体的结构有关 ,通过结构、能量传递和能量匹配对此做了进一步的解释。Some novel binary and ternary complexes of rare earth (Tb) with N-phenylanthranilic acid and 1,10-phenanthroline were synthesized and their compositions were characterized by elemental analysis. The compositions of the complexes have been confirmed to be TbL(3)(.)4H(2)O and TbL3 phen(.)2H(2)O (L : N-phenylanthranilic acid, phen: 1,10-phenanthroline). The spectroscopic properties of the complexes were discussed. The result shows that the luminescence intensities of bina...
