稀土铽-水杨酸配合物的合成及荧光性质

Synthesis and Fluorescence Properties of Rare Earth Terbium-salicylic Acid Complexes

采用共沉淀法分别制备了稀土铽-水杨酸二元配合物以及铽-水杨酸-邻菲罗啉三元配合物。同时,采用溶胶-凝胶法制备了掺杂稀土铽-水杨酸二元配合物的SiO2凝胶玻璃复合发光体。对合成的配合物进行了表征,在紫外光激发下,它们均能发射出铽离子的特征荧光。

Two binary and ternary complexes of rare earth （Tb） with salicylic acid and 1,10-phenanthroline were synthesized, and silica gel glass containing binary complex was prepared by sol-gel method, too. The properties of these complexes were studied. Under the excitation of UV light, these complexes exhibit characteristic luminescence of terbium ion.
