Williamson-Hall analysis of ZnO and Mg doped ZnO nanoparticles prepared via Psidium guajava leaf extract

Abstract

ZnO and Mg doped ZnO nanoparticles (NPs) were synthesized by green method using Psidium guajava leaf extract. X-ray power diffraction studies confirmed that, synthesized nanoparticles were retained the wurtzite hexagonal structure. In addition, the crystallite development in nanostructured ZnO and Mg doped ZnO NPs by X-ray peak broadening analysis. The individual contributions of small crystallite sizes and lattice strain to the peak broadening in pure and Mg doped ZnO NPs were studied using Williamson-Hall (W-H) analysis.
