Tb(TTA)3(TPPO)2/PANI/PVP conductive-luminescence composite nanofibers have been successfully fabricated by the electrospinning technique. The morphologies and properties of the final nanofibers were investigated in detail by scanning electron microscopy (SEM), fluorescence spectroscopy (FL) and broadband dielectric spectrometer measurement. The results show that the bifunctional composite nanofibers possess both good electrical conductivity properties and excellent luminescent properties. The luminescence and electrical conductivity of the composite nanofibers can be tuned by adjusting the amount of Tb complex and PANI. (C) 2017 Elsevier B.V. All rights reserved.
