    Abstract:
    A novel rare earth complex Eu(TTA) (2NH2-phen)3 was synthesized. The Eu complex was blended with poly(N-vinylcarbazole) (PVK) in different weight ratios and spin coated into films. The photoluminescence of Eu(TTA) (2NH2-phen)3 was obtained. Multilayer devices with PVK : Eu(TTA) (2NH2-phen)3 as the active layer were fabricated, and the device structure was ITO/PVK : Eu(TTA) (2NH2-phen)3 / 2,9-dimethyl-4,-diphenyl-1, 10-phenan throline(BCP) /8-hydroxyquinoline aluminum(Alq3)/Al. The influence of Eu(TTA) (2NH2-phen)3 doping concentration on electroluminescence spectroscopy was studied. It was found that the EL spectra do not change with the doping concentration. The spectral overlapping of the emission spectrum of PVK and the absorption spectrum of Eu(TTA) (2NH2-phen)3 is very small. From the above experimental results, it can be demonstrated that the mainly mechanism of Eu(TTA) (2NH2-phen)3 EL is charge carrier directly trapped by ligand.
