摘要：

A novel co-doped rare earth complex Gd0.5Eu0.5(TTA),Dipy was synthesized and chosen as the emitter material in the organic electroluminescent device ITO/PVK: Gd0.5Eu0.5 (TTA)(3) Dipy/PBD/Al. It was proved that there was Forster 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.
