Description :
In the context of science and technology, synthesis nanoparticles reveal new and innovative qualities that are supported by particular features such as size distribution, shape, and application of nano-sized materials. Zinc oxide is currently among the most prominent semiconductor oxides in nanomaterials. In this present work, a chemical precipitation method was used to study the structural, morphological, and optical properties of zinc oxide nanoparticles at room temperature. The obtained samples were characterized after different calcination at temperatures 500℃ and 700℃ by XRD, FTIR spectroscopy, SEM, EDAX, UV-DRS (UV-diffuse reflectance spectroscopy). XRD pattern analysis revealed that the samples exhibit a pure phase with a hexagonal wurtzite structure and their average crystallite sizes are in the nano-range of 23–30 nm. The formation of ZnO nanostructure was confirmed by FTIR analysis. SEM and EDAX exhibited the morphology and highly produced pure ZnO nanoparticles. The optical band gap energy of ZnO nanopowders was computed using UV-visible diffuse reflectance spectroscopy and was found to decrease from 3.31 eV to 3.19 eV. Due to its strong UV absorption, zinc oxide has a variety of beneficial applications, including sunscreen protectors and antiseptic ointments.
