This paper offers insights into optical properties of NiO/Co3O4 nanocomposite, demonstrating how X-ray irradiation affects it which offers information for optoelectronic applications. FTIR results showed existence of chemical bonds that have been presented in our composite. The HRTEM images revealed the presence of clusters of molecules in various shapes and an average grain size approaching 19 nanometers. The optical investigations shows an increase in optical absorbance of a NiO/Co3O4 nanocomposite after irradiation with X-rays up to 60 min. The calculated indirect energy gap of the material increases response to X-ray radiation which attributed to defects in the material's crystal structure.
