Cupric oxide (CuO) thin films were prepared by chemical bath deposition (CBD) method on glass substrates using copper chloride solutions and then annealed at 300 °C in Argon atmosphere in different time intervals of 1 and 2 h. Samples were characterized by FESEM images, XRD and UV-Vis. spectra. We found that the as-grown nanostructured sample has a single-phase (CuO) monoclinic polycrystalline structure with preferred direction of (-111), but after annealing an addition Cu2O phase is also appeared. Analysis of the absorbance data showed that with increasing the annealing time the optical band gap of the sample decreases.

Keywords: Copper oxide, Chemical Bath Deposition (CBD), annealing, nanostructure
