Abstract:
Tb (AUFA) 3 2H 2 O, a rare earth terbium complex,was synthesized by introducing 4-(11-azobenzene-undecyloxy) ferrocene acid (AUFA) as the ligand. This complex was characterized by elemental analysis, MS, IR, Raman, UV spectroscopy and fluorescence spectrophotometry. The complex exhibited ligand-sensitized green emission, and Tb (AUFA) 3 2H 2 O had a higher sensitized luminescence efficiency and a longer lifetime than the other terbium complexes (DPC: 2, 6-Pyridinedicarboxylic acid, Aspirin: 2-ethanoylhydroxybenzoic acid). The organic-inorganic thin film of complexe Tb (AUFA) 3 2H 2 O in nanoTiO 2 was fabricated, and the nanoTiO 2 has been used in the luminescence layer to change the luminescence property of complexes Tb (AUFA) 3 2H 2 O. It was found that there was an efficient energy transfer process between the ligands and metal ions. Moreover, In an ITO/PVK/Tb (AUFA) 3 2H 2 O/Al device, Tb 3+ may be excited by intramolecular energy transfer from the ligand, as observed by electroluminescence. The main emitting peak at 545 nm can be attributed to the 5 D 4 → 7 F 5 transition of the Tb 3+ ion, and this process results in the enhancement of the green emission from the electroluminescence device.
