Abstract:

This study presents a rapid method for synthesizing yttrium oxide nanoparticles (Y2O3-NPs) utilizing ethanol and yttrium oxide (Y2O3). The Y2O3-NPs were analyzed using Fourier transform infrared (FT-IR), ultraviolet spectroscopy (UV-Vis), atomic force microscopy (AFM), scanning electron microscopy (SEM), and X-ray diffraction (XRD).The X-ray diffraction (XRD) analysis revealed that the Y2O3 exhibited a preferred alignment and possessed a cubic crystal structure with a (111) orientation. The Atomic Force Microscopy (AFM) findings indicated the presence of a nanoscale structure characterized by a spherical surface that exhibits excellent dispersibility. The granules were seen to have a consistent size ranging from 19 to 36 nanometers, and the surface had a roughness ranging from 38 to 78 nanometers. The aim of this paper was to examine the features of (Y2O3-NPs) with antifungal and antibacterial activities. Studies on Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella, Escherichia coli, and Candida have shown the effectiveness of NPs as an antibacterial and antifungal agent.
