Abstract: Luminescence-electricity bifunctional Eu(BA)3phen/PANI/PVP composite nanofibers were prepared through the doping of polyaniline(PANI) and rare earth complex in polyrinyl phrrolidone(PVP) via electrospinning. Scanning electron microscope(SEM), energy dispersive spectrometer(EDS), fluorescence spectrometer and broadband dielectric spectrometer were used to characterize the samples. The results indicated that the average diameter of the Eu(BA)3phen/PANI/PVP composite nanofibers was (270±31) nm. Under excitation of 275 nm, the Eu(BA)3phen/PANI/PVP composite nanofibers emitted the predominant emission at 580, 594 and 617 nm, corresponding to 5D07F0, 5D07F1 and 5D07F2 transitions of Eu3+, respectively. The strongest emission intensity occurred when the mass ratios of Eu(BA)3phen: PANI: PVP was 15: 10: 100, the electric conductivity of the composite nanofibers increased with the increase of PANI content, and reached 1.5×10-6 S/cm in high frequency electric field(106 Hz) when the mass ratio of PANI to PVP was 50%.
