Paper Title:
Synthesis and Application of Europium-Doped Complexes in Fluorescence Falsification-Resistant Ink
  Abstract

Fluorescence falsification-resistant ink is one of the most widely used ink in packaging and printing industry. In this paper, europium complexes were synthesized by doping no-fluorescence inert ions Gd3+. IR spectra indicated that these complexes have similar structures, have bonded with the legends. The fluorescence properties indicated that the doping ions Gd3+ can enhance the fluorescence intensities, the best mole ratio of Gd3+ to Eu3+ is 1:9;At last, fluorescence falsification-resistant ink was prepared, the fluorescence ink showed the characteristic emission of Eu3+ , showed invisible in visible light and showed red fluorescence under ultraviolet light.
