Metallic oxides have been largely taken into consideration due to the prospect of modelling the properties of these materials for different applications. The ZnO/CuO nanocomposites were successfully synthesized using photolysis method. The product characterized using XRD, SEM, EDXS, PSA and PL techniques and all the obtained results prepared pure nanoparticles. The calculation of the percentage ratio for metals in compounds was done using EDXS, and the obtained results demonstrated that the Zn ratio was less than Cu. The measurements of XRD, SEM and PSA showed the size of the particles in the nano range by using Scherrer equation and program counting. At 380nm, a strong emission appeared and this indicated that the particles were useful for electronic devices.
