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
