Title: Fluorescence Studies on the Complexes of Europium-Terbium-o -Aminobenzoate-2,2'-dipyridyl
Abstract: A series of mixed rare earth complexes of europium and terbium with o aminobenzoate and 2,2'-dipyridyl were synthesized by the reaction of EuCl 3 and TbCl 3 with o-aminobenzoate and 2,2'-dipyridyl in solution.Their infrared spectra were investigated.The results show that the chemical bonds have been formed between the two ligands with rare earth ions.The fluorescence spectra excited by 351nm UV-light indicate that the fluorescence intensities of europium ions are sensitized by terbium ions and those of terbium ions are quenched by europium ions,but the emission peak positions are unchanged.
