Abstract
ZnO thin film has been deposited onto glass substrates by the spray Pyrolysis method. Different concentrations of Zinc nitrite was used. XRD measurement of the ZnO shows that the films is crystallized in the wurtzite phase. Optical constants were determined from transmittance spectrum using envelope methods. The transmittance was found to decreased 86-65% and refractive index increased with concentration respectively. The energy gap was not affected by concentration and its value (3.28-3.32) eV.
