Abstract
- Pedalium Murex leaf extract was used in this study to create Nickel-doped Cerium oxide (Ni-CeO <subscript>2</subscript> ) nanoparticles at 3 mol% and 5 mol% molar concentrations. The biosynthesized process was applied for the fabrication of Ni-CeO <subscript>2</subscript> NPs. The X-ray diffraction method was used to identify their crystal structure. The XRD measurements showed that the Ni-CeO <subscript>2</subscript> NPs crystallized into the face-centred cubic system. Fourier transform infrared spectral study was applied to explore the molecular vibrations and chemical bonding. The surface texture and chemical ingredients of Ni-CeO <subscript>2</subscript> NPs were studied using field-emission scanning electron microscopy and energy-dispersive X-ray analysis. The EDX mapping spectra illustrate the uniform dispersal of Ce, Ni, and O atoms over the sample's surface. X-ray photoelectron spectroscopy (XPS) was conducted to confirm the chemical state of the Ni-CeO <subscript>2</subscript> NPs. UV-Vis spectrum study was performed to ascertain the photon absorption, bandgap, and Urbach edge of Ni-CeO <subscript>2</subscript> NPs. Photoluminescence (PL) research has been used to study the light-emitting characteristic of Ni-CeO <subscript>2</subscript> NPs. The emissive intensity transition corresponding to Ni-CeO <subscript>2</subscript> NPs was found to increase with the dopant level. The CIE 1931 chromaticity map was plotted to find the aptness of the samples for optical uses. The antifungal ability of Ni-CeO <subscript>2</subscript> NPs was evaluated against the fungi candida albicans and candida krusein with the agar well-diffusion process. The fungicidal activity of the 3 mol% Ni doped CeO <subscript>2</subscript> nanoparticles has shown a maximum zone of inhibition. The experimental findings illustrate the utility of Ni-CeO <subscript>2</subscript> NPs for optical and antifungal applications.<br /> (© 2024.
