Effect of Transition Metal Doping on the Structural, Optical, Thermal Properties, and Antimicrobial Activity of Zinc Oxide Nano Particles

Abstract

Effect of transition metal dopant on structural, optical, thermal properties, and antimicrobial activities of synthesized zinc oxide nanopartcles (ZnO NPs) were investigated in this study. undoped, cobalt, and nickel doped ZnO nanoparticles are successfully synthesized using chemical co-precipitation method. The structure and morphology of these nanoparticles are characterized using X-ray diffraction (XRD), atomic force microscope (AFM), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), as well as an appropriate physical measurement; (Vibrational and electronic) spectroscopy. The Results obtained from XRD indicate that the particles are possessed in wurtzite structure , SEM and AFM studies reveal that the particle size is in the 45-65 nm range. The EDS confirmed the Zn, O, Co, and Ni as major elements of as-synthesized nanoparticles. Ultraviolet-visible (UV-Vis) spectra show that doping Co and Ni, lead to an increase in the absorption edge wavelength and a decrease in the band gap energy, Fourier Transform Infrared (FT-IR) spectra give the presence of functional groups and chemical bonding as well as doped sub-lattice. To measure the biologic activity and potential antimicrobial efficiency of these untapped, Co, and Ni doped ZnO nanoparticles on the Candidates.
