Abstract

This study observed the effect of the addition of iron (Fe) doping on the characteristics of Zinc Oxide (ZnO) nanoparticles.Zn(1-x)Fe(x) with various concentration of x = 0, 2, 4, 6, 8, and 10% was prepared by coprecipitation method using Sodium Hydroxide and Hydrogen Chloride. The effect of adding Fe doping on ZnO was characterized using X-ray Diffraction (XRD) to determine the crystal structure, size, and strain. The analysis result confirmed the absence of additional impurity peaks in the ZnO nanoparticles. Fe doping affects the Zn lattice structure. X-ray diffraction (XRD) study confirms the crystalline Hexagonal structure. Crystal size analysis using Debye Scherrer, UDM, and Halder-Wagner method obtained varying crystal sizes with variations in the concentration of Fe ranging from 19.89-44.72 nm. The crystal size and strain obtained from the Debye Scherrer method are smaller

Abstract

Nickel-doped Zinc Oxide (Zn(1-x)Ni(x)O) nanoparticles have been synthesized by the chemical coprecipitation method. The structure and characteristic of synthesized Ni doped ZnO nanoparticles ware analyzed by X-ray diffraction (XRD) patterns. Crystallite sizes and lattice strain of all samples were calculated using the Scherrer’s formula, Uniform Deformation Model (UDM) and Halder-Wagner (H-W) method. X-ray diffraction analysis confirmed hexagonal cubic structure of Ni-doped ZnO nanoparticles. Also, the crystallite size of the nanoparticles reduces as the nickel concentration increase. The result showed the average crystallite size calculated by Scherrer’s formula (25-29 nm) was smaller than crystallite size using UDM method (51-63) the largest average crystallite size and H-W method (42-47 nm). The lattice strain increases with decreasing crystallite sizes value. The crystal size Ni- doped ZnO nanoparticles decreased with increasing dopant concentration.
