NiO nanoparticles: Phase purification and strain analysis

Abstract

The vast number of applications of transition metal oxide has prompted research in many advanced fields. NiO, which belongs to this category of application oriented research, is discussed in this article. It is confirmed from the XRD analysis that the nanoparticles are in pure phase with space group Fm3¯-m. XRD plot of the intermediate product is also discussed. Average particle size and micro-strain is calculated using Williamson Hall (WH) plot and the results obtained are compared with that obtained from Debye-Scherrer equation.
