چکیده انگلیسی
A novel co-doped rare earth complex Gd05 Eu05 (TTA)3 Dipy was synthesized and chosen as the emitter material in the organic electroluminescent device ITO/PVK:Gd0.5 Eu0.5 (TTA)3 Dipy/PBD/A1. It was proved that there was Förster energy transfer from Gd3+ to Eu3+. The electroluminescent mechanism of the device was proposed by measuring and analyzing the emission and the excitation spectra of the emissive layer. Gd3+ might play the role of promoting the energy transfer from PVK to Eu3+ and inhibiting an intrinsic luminescence of PVK. The device displayed red light with good monochromaticity. The possible energy transfer process of the device was preliminarily discussed.
