Light conversion agents Eu_(l-x)L_x(TTA)_3Phen (L denotes (La~(3+), Gd~(3+), Y~(3+))) complexes were prepared, and the influence of doping ions on fluorescence properties was investigated by elementary analysis, FTIR and fluorescent spectra. The results show that FTIR spectra of Eu_(l-x)L_x(TTA)_3Phen complex system are identical with that of EuTTA_3Phen, which indicates that the complexes (Eu_(l-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: Gd~(3+)>Y~(3+)>La~(3+), and the optimum mole fractions of doping elements are 0.4, 0.2 and 0.5 respectively for Gd~(3+), Y~(3+), La~(3+). Among all the complexes, Eu_(0.6)Gd_(0.4)(TTA)_3Phen complex has the strongest fluorescent intensity. Applying Eu_(0.6)Gd_(0.4)(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).
Ligh (La ~ (3+), Gd ~ (3+), Y ~ (3+))) complexes were prepared, and the influence of doping ions on fluorescence The results show that FTIR spectra of Eu_ (1x) L_x (TTA) _3Phen complex system are identical with that of EuTTA_3Phen, which indicates that the complexes (Eu_ (Ix) L_x (TTA ) _3Phen) are similar to structure (Eu (TTA) _3Phen.) For the above doping elements, co-fluorescence enhancement has the following order: Gd ~ (3+)> Y ~ ), and the optimal mole fractions of doping elements are 0.4, 0.2 and 0.5 respectively for Gd ~ (3+), Y ~ (3+), La ~ (3+). 0.4) (TTA) _3Phen complex with the strongest fluorescent intensity. Applying Eu_ (0.6) Gd_ (0.4) (TTA) _3Phen complex to plastic and printing inks, bright red fluorescence plastic and printing inks were obtained when the content of europium reaches 0.1% (mass fraction).
