摘要

A series of HTTA (thenoyltrifluoroacetone) and TPPO (trioctylphosphine oxide) complexes with different molar ratios of Eu³⁺ to Y³⁺ has been synthesized. Characterization with XRD, IR, UV, elemental analysis and fluorescence spectroscopy has also been carried out. These results showed luminescence of Eu³⁺ complex was enhanced after doped with Y³⁺. The organic–inorganic thin film of complexes Y_1−xEu_x(TTA)₃(TPPO)₂ in nano-TiO₂ was fabricated, and the nano-TiO₂ has been used in the luminescence layer to change the luminescence property of complexes Y_1−xEu_x(TTA)₃(TPPO)₂. It was found that there was an efficient energy transfer process between the ligands and metal ions.
