摘要
以丙烯酸为第一配体,1,10-邻菲啰啉为第二配体,合成铽-丙烯酸-邻菲啰啉三元配合物Tb(AA)3Phen;以二甲基亚砜为稀土配合物Tb(AA)3Phen、三醋酸纤维素(TCA)的共溶剂,采用溶液共混法制备TCA/Tb(AA)3Phen复合膜.红外结果说明:该复合材料为掺杂型高分子稀土复合材料.荧光光谱分析表明:在329 nm波长激发下,Tb(AA)3Phen配合物固体粉末及TCA/Tb(AA)3Phen复合膜都在546 nm处发射出较强的特征荧光,均可呈现出Tb3+离子的特征绿色荧光,但TCA基体对Tb(AA)3Phen配合物中丙烯酸配体的吸收跃迁及发射跃迁均有一定影响.
A ternary complex, Tb (AA)3Phen, was synthesized from acrylic acid (AA) as the first ligand and 1,10 - phenanthroline as the second ligand. Tri - cellulose acetate (TCA)/Tb (AA) 3 Phen Composite was prepared by the method of solution blend, with dimethyl sulfoxide (DMSO) as the mutual solvent. The Fourier transform infrared spectroscopy (FT- IR) results indicated that the TCA/Tb (AA)3Phen composite was doped material. Results of the fluorescence spectroscopy showed that both the Tb (AA) 3 Phen complex powder and the Tb (AA)3 Phen composite could emit characteristic fluorescence at 546 nm (kex = 329 nm) , which displayed green fluorescence characteristic of Tb3+ ion. However, the TCA matrix has some effects on the absorption transition and emissive transition of acrylic acid ligand in Tb (AA) 3 Phen complex.
