Abstract

In this study, γ-Al2O3: Eu Nanoparticles synthesized by Sol-Gel method were manufactured at 800 °C using X-ray diffraction pattern analysis (XRD), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). X-ray diffraction energy (EDX) and Fourier transform infrared spectrum (FTIR), the formation and construction of these Nanoparticles are investigated. The XRD and SEM images confirmed the correct formation of the material structure and the uniformity of the formed Nanoparticles, respectively, images of TEM showed the the average crystallite size is obtained to be about 10 nm, EDX violated the impure presence of these Nanoparticles, created an infrared absorption spectrum, and examined the binding of nanoparticle bonds. antibacterial properties of γ-Al2O3: Eu Nanoparticles led to resistance to activity of 11 types of microorganisms. Results demonstrated that prepared Al2O3:Eu NPs have maximum antibacterial activity against microorganisms (15.63 μg/ml) and Al2O3:Eu have inhibitory effect against tested microorganisms. For Al2O3;Eu NPs, the disk diffusion test proved that the highest growth inhibition zone was related to Staphylococcus aurEus and Escherichia coli.
