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560,597,641nm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.
The ternary complex of samarium with N-phenylanthranilic acid (N-HPA) and phenanthroline (phen) has been synthesized in ethanol solution 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 3+ at 560,597 and 641 nm,which indicated that the triplet energy levels of N-phenyl aminobenzoic acid match the lowest excitation energy levels of Sm 3+ and the complex has good luminescence properties.
