Nickel oxide specimens have recently garnered significant attention due to their promising potential in energy storage applications. This study reports on the synthesis of nickel oxide materials via a facile sol-gel method, followed by a comprehensive characterization using methods such as X-ray diffraction (XRD), scanning electron microscopy (SEM)

Nanoparticles demonstrate unique optical properties that have sparked considerable interest in their application for diverse technological fields. Upconversion nanoparticles (UCNPs), a particular class of nanomaterials, exhibit the remarkable ability to convert near-infrared light into visible light. This phenomenon has opened vast possibilities in
