Abstract: Eu(TTA)₃phen/vinyl pyrrolidone (PVP) composite nanofibers have been prepared by electrospinning technique. The spectral properties of Eu(TTA)₃phen/PVP composite nanofibers have been studied, as compared to that of Eu(TTA)₃phen powders. The excitation of Eu(TTA)₃phen/PVP systems by UV light results in a ligand-to-metal energy transfer and the emission spectra display characteristic luminescence of the central ions (⁵D₀→7F₂ for Eu³⁺). Photoluminescence measurements show that Eu(TTA)₃phen/PVP nanofibers have higher intensity and longer lifetime than that of Eu(TTA)₃phen powders because of the influence of PVP on the coordinative environment of lanthanide ions.
