Abstract :

In this research work, the synthesis of hybrid silver (Ag) and copper oxide (CuO) was carried out by solvo/hydrothermal-microwave process in the deionized water (H2O), ethanol (C2H6O) and ethylene glycol (C2H6O2) solvents and the effects of solvent type on structural and optical properties were studied. The obtained samples were characterized by X-ray diffractometer (XRD), scanning and transmission electron microscopies (SEM and TEM), photoluminescence (PL) and absorption spectroscopies (UV-Vis). The XRD study of the samples showed presence of Ag (Cubic) and CuO (Monoclinic (phase in the obtained materials. Elemental analysis (EDS) showed presence of Ag, Cu, and O in the samples. Electron microscopes images revealed non-regular and impacted samples of Ag and CuO. The intensity of emission band of synthesized nanostructures in ethanol and ethylene glycol were reduced and it was observed a shift in the absorption edge towards lower wavelength (blue shift) in compared with synthesized samples in deionized water.
