AbstractRare earth ternary complex of Eu3+ with 4,7-2NH(2) Phenanthroline and HTTA was synthesized, and it contents and structures were postulated based on elemental analysis, FT-IR spectra and UV-vis spectra. Results show that the complex of Eu(III) emit strong red luminescence when excited by UV light. Eu(TTA)(2NH(2)-Phen)(3) has the higher sensitized luminescent efficiency and longer lifetime. In device ITO/PVK/Eu(TTA)(2NH(2)-Phen)(3)/Al, EU3+ may be excited by intramolecular energy transfer from ligands as observed by electroluminescence. The main emitting peak at 614 nm can be attributed to the transition of D-5(0) -> F-7(2) of Eu3+ ion and this process results in the enhancement of red emission from electroluminescence device.
