One-dimensional electrospun lead oxide nanofibers synthesized by a simple electrospinning technique. The prepared lead oxide nanofibers investigated by using TG/DTA, FTIR, Raman, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area analyzer, scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX), atomic force microscopy (AFM), Transmission electron microscopy (TEM), and impedance spectroscopy techniques. TG/DTA results confirmed the thermal behavior of the as-spun nanofibers. XRD, FTIR, and Raman spectra results, respectively, confirm the formation of pure orthorhombic crystalline phase and structural coordination of the lead oxide (beta-PbO) nanofibers. The BET specific surface area of beta-PbO nanofibers sample is found to be 51.23 m(2) g(-1). SEM and AFM micrographs showed the formation of beta-PbO nanofibers with a diameter of 85-300 nm. The impedance measurements of lead oxide nanofibers as a function of temperature, 25-150 degrees C, was evaluated by analyzing the measured impedance data using the winfit software. The electrical conductivity of the lead oxide (beta-PbO) nanofibers evaluated by analyzing the measured impedance data using the winfit software is found to be 5.68 x 10(-6) S cm(-1) at 150 degrees C. Also, an activation energy (E-a) for the migration of the charge carrier evaluated from the temperature dependence of conductivity plot is found to be 0.27 eV. The temperature dependence AC conductivity of beta-PbO nanofibers was evaluated using the measured impedance data and sample dimension. The observed variation of high-frequency AC conductivity attributed to the hopping electrons between the adjacent sites. (C) 2017 Elsevier B.V. All rights reserved.
