| Popis: | We have synthesized CuO and Cu2O nanoparticles by sol–gel method for possible applications in photovoltaic or energy storage devices. XRD pattern clearly indicates the formation of pure CuO and Cu2O nanostructures with an average crystallite size of 31.9 and 39.3 nm, respectively. FTIR spectroscopy analysis also confirms the formation of pure CuO and Cu2O nanoparticles. The optical energy band gap was calculated by tauc’s plot for CuO and Cu2O are 2.18 eV and 1.62 eV respectively. The broad and visible emission peaks in the photoluminescence spectra are associated with the superposition of various defects present in the corresponding CuO and Cu2O nanostructures. |
