摘 要：<正>The binary complexes of europium with benzoic acid and its derivatives （phthalic acid, m-phthalic acid, o-aminobenzoic acid, salicylic acid, and sulfosalicylic acid） were synthesized and their compositions were identified by elemental analyses. UV and IR of the complexes have been investigated. The UV spectra indicated that the complexes’ ultraviolet absorption were mainly the ligands’ absorption. The IR spectra showed mat the IR spectra of complexes are different from those of free ligands. The fluorescence properties of them were investigated by using luminescence spectroscopy, the results showed that only three complexes appear as better luminescence, they were Eu-benzoic acid, Eu-m-phthalic acid and Eu-phthalic acid, while the others exhibited the ligands’ wideband emission.
