Abstract

Quaternary europium complex EuxGd(1-x)(POA)(TTA)2Phen were synthesized by doping no-fluorescent inert ions Gd3+with ligands of POA, α-thenoyltrifluoroacetone (TTA), and o-phenanthroline(Phen).IR spectra was studied , indicate that these complexes have similar structures, have bonded with the ligands.The fluorescent properties,the influence of fluorescent property by doping ions Gd3+were studied. The results showed that the doping ions Gd3+can enhance the fluorescence intensities, the best mole ratio of europium to gadolinium is 6:4.
