SYNTHESIS, CHARACTERIZATION AND MICROSTRUCTURAL EVALUATION OF ZnO NANOPARTICLES BY WILLIAM-HALL AND SIZE-STRAIN PLOT METHODS

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

Automated summary

Zinc oxide nanoparticles were produced at various calcination temperatures, with high surface area and small particle radius. The Williamson-Hall technique and size-strain approach were used to measure crystallite size and strain in ZnO nanoparticles. The experimental results, based on SEM and XRD, showed good agreement in crystal size of ZnO NPs prepared at different calcination temperatures.
