Abstract:

Eleven europium complexes doped other metal ions with 2,3 - pyrazine dicarboxylic acid had been synthesized and characterized by elemental analyses, rare earth EDTA titration, IR, UV and fluorescence spectra. They were EuL1.5•5H2O, Eu0.5Ln0.5 L1.5•5H2O (Ln3+=La3+, Y3+, Gd3+), EuML2.5•8H2O (M2+= Mg2+, Ca2+, Sr2+, Ba2+, Co2+, Ni2+, Zn2+). Doped metal ions could enhanced the fluorescence of Eu3+ complex, and the order of the fluorescence enhancement was Zn2+>La3+>Gd3+>Y3+; Mg2+> Sr2+>Ca2+>Ba2+. And doped with Co2+ and Ni2+ made the Eu3+ luminescence quenched, which the luminous intensity was almost zero.
