To study the structural properties of cobalt doped tin oxide nanostructured by using Williamson-Hall and size-strain plot methodology

Abstract

Nanocomposites are the materials which are synthesized with the combination of two or more different materials comprising multiple domains and at least one phase domain in the nanometre range (1 nm-100 nm). Nanocomposites materials have significant advanced properties and application relative to individual nonmaterial adhere cumulative properties of host and guest material. In present work, nanocomposite of tin oxide doped with cobalt oxide was synthesized by applying chemical route method assisted by microwave. Various characterization techniques were applied to characterize the as-synthesized and calcined samples of Cobalt doped SnO 2 nanostructured materials such that diffraction caused by X-rays, infrared spectroscopy (IR). From diffraction caused by X-rays result analysis, it was observed that cobalt is substituted into the lattice position of the parent atom of Tin. The FTIR photograph study reveals that the presence of both constituents in the synthesized samples at their relative position (cm −1 ). The estimated crystallite/grain size of Cobalt doped SnO 2 nanostructured materials obtained from Debye-Scherrer formula was compared with Williamson Hall method and in addition to that the various peak broadening were investigated. From experimental results it was concluded that the crystallite/grain size of nanostructured material were decrease with increasing calcinations temperature due to lattice strain and dislocation in atomic structure from the rearrangement bonding connection between the atoms of tin oxide and cobalt.
