摘要
A novel rare earth complex Eu(TTA)2(N-HPA)Phen (TTA=thenoyltrifluoroacetone, N-HPA=N-phenylanthranilic acid, and phen=1,10-phenathroline), which contains three different ligands, was synthesized. The Eu complex was blended with poly N-vinylcarbazole (PVK) in different weight ratios and spin coated into films. The luminescence properties of films were investigated and energy transfer between PVK and the complex was discussed. Multilayer structural devices consisting of ITO/PVK∶Eu(TTA)2(N-HPA)phen/BCP/Alq3/A1 were fabricated with PVK∶Eu(TTA)2(N-HPA) as light-emitting layer. Increasing the concentration of Eu in the PVK thin film would inhibit the emission of PVK to different degrees. Finally, the pure red luminescence of europium(Ⅲ) was observed when the doping weight ratio was approximately 1∶5, which indicated an effective energy transfer from PVK to rare earth complex.
