Abstract

The study prepared new Copper sodium borate oxide CSmBO nanocomposite thin films using a solvothermal synthesis method and the annealing process occurred at 350°C for 3 hours. The study characterized the films using FESEM, EDX, and UV spectroscopy. Based on the FESEM analysis, the films were uniform and dense, with nanoparticles which range from 21.49 to 96.51 nm in size. EDX confirmed the elemental composition of the CSmBO nanostructures, validating the successful incorporation of copper, samarium, and boron. (XRD) diffraction patterns show up that forming a Crystal phase with high levels of strain and blemish is due to nanoparticle gathering. The synthesized nanocomposites exhibited a remarkable tunability in morphology and structure. UV-Vis spectroscopy revealed a broad optical absorption spectrum with a maximum absorbance peak at 600 nm, demonstrating the potential of the CSmBO nanocomposite thin films for optoelectronic applications. The band gap (Eg) was 2.03 eV and the Urbach energy (Eu) 0.15 eV which indicates a relatively lower degree of localise band tail states. Successfully fabricating CSMBO nanocomposite thin films with tunable features highlights the potential of this composite for many optoelectronic implementation, inclusively solar energy harvesting, light-emitting and diodes photo catalysis.
