X-ray Analysis by Williamson-Hall Methods of Pure and Doped ZnO Nanoparticles

Abstract

Zn _0.8Cr_XNi_0.2-X  (where X=0, 0.05, 0.1, 0.15, 0.2) nanopowders, by the citrate path, were synthesized by the auto-combustion sol-gel method and heat-treated at 700 ◦C. X-ray diffraction (XRD) analysis and electron microscopy with high-resolution scanning microscopy (SEM) have characterized the samples collected. In addition, an X-ray energy dispersive (EDX) study was carried out. Using Scherrer's formula and the Williamson-Hall (W-H) analysis, the average crystallite size and lattice strain were analyzed, assuming the (Uniform Deformation Model) (UDM), (Uniform Deformation Stress Model), (UDSM) and (The Energy Density Model for Uniform Deformation) (UDEDM). The results reveled that there was a strong association between the average of crystallite size and the lattice strain calculated from the different studies.
