Abstract
Zinc-doped yttrium oxide nanopowders of various doping concentrations have been successfully synthesized by simple methods like sol–gel, solvothermal and wetchemical methods. Structural property is analysed by X-ray powder diffraction (XRD). The presence of elements is confirmed by FTIR studies. Conductivity and dielectric behaviour of the samples are analysed by impedance spectroscopy. The effects of doping concentration and method of preparation on the crystallinity, the dielectric constant and the electrical properties of zinc-doped Y2O3 nanomaterials are investigated and presented in this paper. XRD analysis shows the crystalline nature of the samples except the one prepared by solvothermal method. Also, the same sample is found to have more conductivity in the order of 5.04 × 10−7 Scm−1 when compared with the samples prepared by other methods and of different doping concentration.
