| Abstract: | The new rare earth complexes of Eu(TTA)_3, phen, Eu(Y) (TTA)_3 phen were synthesized. Its fluorescence spectra properties and fluorescence-enhanced phenomenon have been studied. The complexes assume bright red color (λ_(em) = 619nm) at UV (λ_(ex) = 386nm). The UV fluorescent falsification-resistant inks were prepared. |
