摘要：

We have investigated the post heat treatment effect of electrochemically prepared cupric oxide (CuO) thin films. The films were annealed at different temperatures ranging from 200 to 400 degrees C in air medium. The structural, optical, compositional and morphological properties of annealed CuO thin films were studied. X-ray diffraction patterns revealed that the as-deposited film exhibited cubic with structure along the (111) preferential orientation. Annealing induced further grain growth and tightened the grain size distribution was envisaged. The morphological properties and surface roughness were studied using scanning electron microscopy and atomic force microscopy. Optical properties of the films were analyzed by recording transmission, absorption and reflection spectra. Optical band gap of as-deposited and annealed CuO thin films were estimated by conventional method.
