Abstract
Zinc oxide nanoparticles (ZnO NPs) are indispensable materials for spectral and optical phenomena, prepared by a chemical precipitation method. We studied their properties resulting from different dopants in the nanoscale. The samples' structure, texture, energy band, and photoluminescence were examined using XRD, TEM, FTIR, PL, and UV–VIS spectroscopy. XRD shows the single hexagonal Wurtzite with crystallite sizes from 10.1 to 17.8 nm and the spherical shape particles. The octahedral sites at 470–489 cm−1 and the tetrahedral sites at 616 cm−1 were observed in the FTIR studies. PL showed a wider bandgap, better UV emission, and decreased defect density of the Fe doped than that of the pristine one. Fe-doped ZnO NPs are more active than pristine ZnO NPs for their quenching or absorbing properties, indicating their antibiotic properties.
