摘要:

采用常规溶液法合成了钐、N-苯基邻氨基苯甲酸(N-HPA)和邻菲罗啉(phen)的稀土钐配合物Sm(N-PA)3phen,并采用元素分析、紫外光谱、红外光谱初步对配合物进行了结构表征,研究其荧光性能.结果表明,配合物荧光发射光谱在560,597,641 nm显示出钐离子强特征荧光发射峰,说明N-苯基邻氨基苯甲酸的三重态能级与Sm3+的最低激发态能级匹配,配合物有较好的发光性能.

Abstract:

The ternary complex of samarium with N-phenylanthranilic acid (N-HPA) and phenanthroline (phen) has been synthesized in ethanol water and characterized by Fourier transform infrared spectrum (FTIR), ultraviolet spectroscopy (UV-Vis) and fluorescence spectrophotometer (FS), respectively. The fluorescence emission spectra of the complex showed strong typical sharp characteristic emission peaks of Sm at 560, 597 and 641 nm, which indicates that the triplet energy levels of N-phenyl aminobenzoic acid match the lowest excitation energy levels of Sm3+ and the complex has good luminescence properties.

Key words: rare earth complexes, Sm, N-phenylanthranilic acid, fluorescence properties
