| 摘 要： | 以丙烯酸为第-配体,1,10-邻菲哆啉为第二配体,合成铽-丙烯酸-邻菲哆啉三元配合物Tb（AA）,Phen;以二甲基亚砜为稀土配合物Tb（AA）,Phen、三醋酸纤维素（TCA）的共溶剂,采用溶液共混法制备TCA／Tb（AA）,Phen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329nm波长激发下,Tb（AA）,Phen配合物固体粉末及TCA／Tb（AA）,Phen复合膜都在546nm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）,Phen配合物中丙烯酸配体的吸收跃迁及发射跃迁均有-定影响．

| Abstract: | 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. |
