Preparation and study of spectral analyses and optical properties of nanopole sensitive to light of hydrogen fuel production

In this paper, nano NiO thin films were prepared onto glass substrates by ultrasonic spraying material. A second harmonic Nd: YAG laser (532 nm, 25 mW) has been used for annealing this film. X-ray diffraction (XRD) results indicate that prepared films are polycrystalline structure with (111, 200) plane reflections, it was found that the prepared films have high transmittance in the visible region and optical band gap was 4 eV. The surface morphology of the nano NiO as measured by atomic force microscope (AFM) showed that the surface roughness.
