Synthesis, characterization and microstructural evaluation of ZnO nanoparticles by William-Hall and size-strain plot methods

ABSTRACT. At various calcination temperatures 450, 550 and 650 °C, zinc oxide nanoparticles were produced. Calcinated ZnO has high surface area as the BET was 119.12 m2g–1 average particle radius calculated to be 1.16 nm. The dimension of crystallites straining in nanoparticles' diffraction peaks remained measured. Williamson–Hall (W–H) technique besides size–strain approach stayed used. For each XRD reflection peaks, physical characteristics like strain stress computed. Towards regulate magnitude crystallites, are used that is good agreement with size determine from SEM it 22.6, 26.6 32.6 nm for calcinated at oC, individually. Using W–H plot modify subversion shape, assuming an unvarying distortion model (UDM), deformation (USDM), energy density (UDEDM), plan (SSP) this. Scherrer methods match well crystal NPs determined using plots SSP technique.
