ZnO:CuO Nanocomposite Produced by Laser Ablation in Water for Antibacterial Activity

Abstract

Zinc oxide (ZnO) and copper oxide (CuO) nanoparticles were created using Nd-YAG pulse ablation, and they were subsequently examinedas colloidal solutions. The produced nanoparticles were examined for UV-VIS absorption using transmission electron microscopy (TEM) andFourier transform infrared spectroscopy (FTIR) (TEM). The production of zinc oxide and copper oxide nanoparticles is shown by FTIRcharacterization. the subsequent tests for UV-VIS absorption. According to TEM, the nanoparticle sizes varied from (30) nm for zinc oxide to(40) nm for copper oxide. X-ray diffraction was used to describe the films' structure (XRD)The X-ray showed the monoclinic crystallinestructure of CuO and the hexagonal wurtzite phase of ZnO. Due to their antibacterial properties, copper oxide nanoparticles with a size rangeof 54.35–40.16 nm and zinc oxide nanoparticles with a size range of 36.16 nm were found to display FESM.
