| The optical properties of lead oxide samples prepared using thermal evaporation technique on unheated glass substrates with different film thicknesses have been studied. The structural characteristics of a lead oxide sample was investigated using X-ray diffraction and it is confirmed to be in the amorphous state. The optical properties of the prepared films were studied by transmittance and reflectance measurements, and the integrated transmittance (TUV, TVIS and TSol) in ultraviolet, visible and solar regions was calculated and found to be affected by film thickness. The dependence of absorption coefficient on wavelength was also reported. The energy gap was calculated and has been observed around 3.7 eV. |
