Investigating the structural, spectroscopic, photoluminescence, and antibacterial characteristics of biosynthesized cobalt-infused cerium oxide nanoparticles
Source abstract
Abstract
Cerium oxide nanoparticles infused (doped) with two distinct cobalt concentrations (3wt% and 5wt%), were fabricated usingPedalium murexleaf extract. Our findings showed the presence of a cubic fluorite structure and evenly distributed Co(3%)–CeO2and Co(3%)–CeO2nanoparticles (NPs), with average crystallite sizes of 82 and 83 nm and bandgaps of 3.07 and 3.03 eV. Co-doped CeO2NPs efficiently absorb UV light while preserving their transparency in the visible light, indicating their suitability for UV filters. The presence of prominent emission peaks in the photoluminescence spectra at 648 nm is useful for optical display systems. CIE chromaticity and Correlated Color Temperature charts were used to analyze the color output. The antibacterial abilities were evaluated against pathogenic bacteria using the agar well diffusion process. The Co–CeO2NPs have shown significant antibacterial effects against harmful bacteria. The results demonstrate the potential use of Co–CeO2NPs in optical display systems and biological applications.Graphical abstract
