Abstract

Cu2O/CuO nanocomposite has been synthesised by sol–gel route. The microstructural and optical absorption analyses were carried out using X-ray diffraction (XRD) and UV–visible spectrophotometer. The presence of Cu2O in Cu2O/CuO nanocomposite did not affect the microstructure of CuO. However, the optical absorption band of CuO was influenced in the presence of Cu2O in Cu2O/CuO nanocomposite. The values of indirect and direct band gap of CuO in Cu2O/CuO nanocomposite showed higher red shift and lower blue shift when compared with the corresponding reported values of CuO nanoparticles.
