Thin film of CuO has been deposited on a glass substrate by chemical bath deposition method. The CuO thin films are found to be uniform, smooth, and well adherent to the substrate. The films are characterized for their optical characteristics. Structural study through XRD spectrum showed that CuO films are crystalline nature. Compositional analysis by EDAX, the composition and chemical constituents of the film is estimated and is tachometric Surface morphology study through SEM photographs gave the surface nature which was uniform and smooth.
