Abstract: In the preparation of Fe doped ZnO a novel process is used with different doping concentrations from 2% to 10% by surfactant assisted combustion synthesis. The synthesized samples were characterized with X-ray diffraction particle analyzer and TEM. From X-ray diffraction, it was observed Fe-doped ZnO nanoparticles (NPs) have hexagonal wurtzite structure and further crystallite sizes were decreased with increasing doping concentrations. Transmission electron microscopy (TEM) showed that powder was polycrystalline in nature with random distribution of nano grained Fe doped ZnO. Using X-ray broadening crystalline development in the Fe doped ZnO-NPs was investigated. The crystallite sizes and lattice strain on the peak broadening of Fe doped ZnO-NPs were studied using Williamson-Hall (W-H) analysis and size- strain plot. Strain, stress and energy density parameters were calculated for the XRD peaks of all the samples using (UDM), uniform stress deformation model (USDM), uniform deformation energy density model (UDEDM) and by the size-strain plot method (SSP). The results of mean particle size of Fe doped ZnO-NPs showed an inter correlation with W-H analysis, SSP, and TEM results.
