The Eu(Ⅲ) complex and new Schiff base ligand of taurine and 2-acetylbenzimidazole were synthesized in methyl alcohol.The structure of the complex was determined as Eu₂L₃(NO₃)₃(L=C₁₁H₁₂N₃O₃S) by chemical and elemental analysis,¹H NMR,IR,mass spectrometry,laser Raman and three-dimension fluorescene spectrometry.The main fluorescence emission of the complex was Eu³⁺ perturbation ligand to light-emitting,along with the Eu³⁺ center narrow-band luminescence.When the λ_ex=330.0 nm,the Eu³⁺ ion narrow-band fluorescence is emitted;when λ_ex=410.0 nm,the Eu³⁺ produces the 525.0 nm emission band.
