In the present study, the pure ZnO nanoparticles was prepared by sol–gel method using zinc acetate dehydrate (Zn (Ac) 2·2H2O), as precursor and doped with metal ions and nonmetal ions like Vanadium, Dysprosium and Sulfur ions. The obtained ZnO nanoparticles have been studied using X-ray diffraction (XRD), which indicates the presence of hexagonal Wurtzite structure for pure and single doped and tri-doped ZnO-NPs. The effect of different dopent on crystallite sizes and lattice strain of ZnO-NPs were studied by using Williamson-Hall (W-H) analysis and Size-Strain plot method. We also calculate crystallite sizes of doped and pure ZnO NPs with the help of Debye-Scherrer method. The three form of W-H plot i.e. UDM, USDM and UDEDM and SSP model were used to calculated parameters such as strain, stress and energy density more precisely for all the reflection peaks of XRD corresponding to Wurtzite hexagonal phase of ZnO lying in the range 2θ =15–80 degree.
