Abstract

Rare earth ternary complexes Tb_1-xEu_x(TTA)₃Phen (x = 0,0.25, 0.5, 0.75, 1.0) were synthesized and characterized by DTA-TG, XRD and infrared (IR). The photophysical properties of these complexes were studied in detail using ultraviolet absorption spectra and fluorescent spectra. Ultraviolet absorption showed that the energy absorption of the complexes mostly came from ligands. Infrared spectra of Tb_{1 - x}Eu_x(TTA)₃ Phen complexes were similar to the pure complexes. TG curves proved that the complexes were stable. Tb³⁺ emission was almost quenched and the Eu³⁺ emission was enhanced by codoping the complexes. The Tb³⁺ ion acted as an energy transfer bridge that helped energy transfer from poly (N-vinylcar-bazole (PVK) to Eu³⁺. In addition, their PL and EL properties were systematically studied.
