Abstract

Light conversion agents Eu1−x L x (TTA)3Phen (L denotes La3+, Gd3+, Y3+) complexes were prepared, and the influence of doping ions on fluoresence properties was investigated by elementary analysis, FTIR and fluorescent spectra. The results show that FTIR spectra of Eu1−x L x (TTA)3Phen complex system are identical with that of EuTTA3Phen, which indicates that the complexes Eu1−x L x (TTA)3Phen are similar in structure to Eu (TTA)3Phen. For the above doping elements, co-fluorescence enhancement has the following order: Gd3+ > Y3+>La3+, and the optimum mole fractions of doping elements are 0.4, 0.2 and 0.5 respectively for Gd3+, Y3+, La3+. Among all the complexes, Eu0.6Gd0.4(TTA)3Phen complex has the strongest fluorescent intensity. Applying Eu0.6Gd0.4(TTA)3Phen complex to plastic and printing inks, bright red fluorescence plastic and printing inks are obtained when the content of europium reaches 0.1% (mass fraction).
