“…Figure 6 presents the absorption coefficient data against wavelength for the CuO films prepared by CBD and annealed at two different temperatures. Equation (3) below was used to calculate the absorption coefficient values [30]: (7) where d and T are respectively the thickness and the transmittance of the thin film. Figure 6 depicts the absorption coefficient versus wavelength for CuO thin films prepared by the CBD technique and annealed at two temperatures.…”

“…As a result, numerous studies have been conducted in recent years to develop novel CuO nano-structures with controlled morphologies and novel physical and chemical properties. Numerous CuO nanostructures including nanowires [6], nanosheets [7], nanotubes [8], nanorods [9] and nanoneedle [10] have been synthesized using various methods such as electro-deposition [11] hydrothermal treatment [12], thermal evaporation [13], thermal oxidation [14], quick-precipitation [15], solution synthesis [16] and high-temperature combustion [17] …etc.…”

 The chemical bath deposited method was used because its simple, easy, and inexpensive.  A rod-like nano-structure of Copper Oxide was prepared.  The effect of annealing temperature (400 and 500) was studied.In this paper, we reported that the annealing at temperatures of 400 and 500 oC in the air for 2 hours led to the formation of rod-like structures of cupric oxide thin films prepared by the chemical bath deposition technique. The structure and the optical properties of the prepared thin films were studied to investigate the role of annealing on the films. The morphology of the as-deposited CuO films is almost structureless. However, the films are converted to rod-like shapes nanostructures after annealing, as confirmed by scanning electron microscopy. The xray analysis showed that the thin films of copper oxide nano-structures have a monoclinic crystallinity preferred in the ( 110), (002), and ( 111) directions, and the crystallinity increases after annealing. Furthermore, the bandgap values after annealing are reduced from 2.1 to 1.61 and 1.63 eV as determined by optical analysis utilizing UV-VIS spectroscopy.
