Abstract
One-dimensional, elemental doped CdO nanofibers have emerged as marvelous fibrous materials for translation into energy harvesting devices technology, however very little is reported about these materials. This study describes the fabrication and characterization of Nix/(CdO)1-x doped nanofibers, with foremost emphasis on the dielectric properties for a range of Ni concentrations (0 ≤ x ≤ 15 wt%), produced by a dc-driven electrospinning technique. X-ray diffraction, energy dispersive spectroscopy, and fourier-transform infra-red spectroscopyprovide a strong signature on the crystalline cubic phase and formation of contamination free CdO nanofibers. Ni doping leads to altering the electrical, optical, and morphological characteristics of the nanofibers. The grain size and average diameter of the fibers were varied from 22 to 11 nm and 70–120 nm respectively while the spectral emission of the photon energies spanned over 1.7–1.2 eV. The impedance, dielectric properties, and conductivity were strongly affected by Ni doping with the smallest charge transfer resistance and the highest charge separation obtained for x = 15% Ni. A comprehensive analysis of metal doped Nix/(CdO)1-x electrospun nanofibers with tuneable characteristics will offer innovative strategies and opportunities for possible sustainable energy production, and creative solutions to biomedical, healthcare, sensor devices, and environmental problems.
