Luminescence Properties of Eu (TTA)_3(H_2O)_2 Doped with DNA-CTMA and Its Application in Fluorescent Inkjet Ink

摘要

In this chapter, the Eu(TTA)_3(H_2O)_2 complex was synthesized and the luminescence property was analyzed. The interaction between Eu(TTA)_3(H_2O)_2 and DNA-CTMA complex both in solution and films state were studied. In addition, the fluorescent inkjet ink sample was prepared using the Eu(TTA)_3 (H_2O)_2 complex doped with DNA-CTMA as the fluorescent dye. The results showed that the main emission wavelength of Eu(TTA)_3 (H_2O)_2 complex was 614 nm, and the emission intensity was the highest when the concentration reached 60%. In the film state, the fluorescence of the Eu(TTA)_3(H_2O)_2 complex doped with DNA-CTMA compound was enhanced greatly. Moreover, the prepared inkjet ink sample showed good printability and anti-false effect.
