Abstract: Copper oxide (CuO) thin films have been synthesized on to glass substrates at different temperatures in the range 250-450 C by spray pyrolysis technique from aqueous solution using cupric acetate Cu(CH3COO)2H2O as a precursor. The structure of the deposited CuO thin films characterized by X-ray diffraction, the surface morphology was observed by a scanning electron microscope, the presence of elements was detected by energy dispersive X-ray analysis, the optical transmission spectra was recorded by ultraviolet-visible spectroscopy and electrical resistivity was studied by Van-der Pauw method. All the CuO thin films, irrespective of growth temperature, showed a monoclinic structure with the main CuO (111) orientation, and the crystallite size was about 8.4784 for the thin film synthesized at 350 C. The optical transmission of the as-deposited film is found to decrease with the increase of substrate temperature, the optical band gap of the thin films varies from 1.90 to 1.60 eV and the room temperature electrical resistivity varies from 30 to18 Ohmcm for the films grown at different substrate temperatures.

 

Keywords: Spray pyrolysis, CuO, Band gap, Substrate temperature.
