[The luminescence character of Eu complexes with derivatives of benzoic acid and different second ligands].
Synthesize eight rare earth europium complexes with derivatives of benzoic acid and different second ligands. We obtained luminescence spectra of these complexes. Although their Eu3+ have about local surrounding symmetry, luminescent intensities are different each other. Because of matching of energy level the complexes with phen is better than with bipy and through the variety structure of spectra show the complexity of Eu3+ hypersensitive transition.
