Abstract

Pristine (pure) ZnO and Zn₁₋_xFe_xO (with Fe = 0.05, 0.10, and 0.15) nanoparticles (NPs) were successfully prepared by green synthesis using aloe vera gel. The x-ray diffraction (XRD), Field emission scanning electron microscope, ultraviolet-visible, photoluminescence (PL), and vibrating sample magnetometer (VSM) were employed to investigate the structural, optical, and magnetic properties of Zn₁₋_xFe_xO NPs. Rietveld refined XRD data revealed that Zn₁₋_xFe_xO NPs have hexagonal wurtzite structures with space group P63mc. Fe-doping resulted in a decrease in the average grain size. The value of the E_g decreased from 2.49 to 2.17 eV with an increase in Fe³⁺ content. A blue shift in band edge emission shift toward lower wavelength (x = 0.00 to 0.05) and red-shift for (x > 0.05) PL spectra. A ferromagnetic behavior with enhancement in saturation magnetization was observed with Fe³⁺ doping. By breaking down the bacterial cell wall and altering the genetic makeup of the cells, Zn₁₋_xFe_xO NPs effectively eradicate Klebsiella pneumonia and Staphylococcus aureus in antimicrobial assessment.

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
