An investigation on structural, dielectric and optical properties of pure and Fe-doped CuO nanoparticles for optoelectronic device applications

This work describes the straightforward solvothermal microwave irradiation approach utilized to create pure and variable quantities of Fe doped CuO nanoparticles, as well as the experimental methods used to characterize their structural properties. The chemical, physical, and structural features of the nanoparticles were characterized using a wide variety of methods. The crystal structure, lattice properties, and crystallite size of the pure and Fe-doped CuO nanoparticles produced were confirmed by powder X-ray diffraction investigation. Analyzing the produced nanoparticles using Energy Dispersive X-ray Absorptiometry confirmed their atomic percentage and stoichiometry. The band gap and absorption were calculated from the items' measured UV-visible spectra. Photoluminescence tests confirmed the materials' stated green emission. Surface morphology and nanoparticles quality is assessed by SEM. Transmission electron microscopy can assess particle size and dispersion. The temperature dependence of the dielectric characteristics of nanoparticles was studied. It has been shown that CuO nanoparticles, both undoped and Fe-doped possess applications like power generation, circuitry, telecommunication, optical and photovoltaic device.
