Özet

The optical constants (refractive index, n; extinction coefficient, k and dielectric constant, epsilon) of the complexes of oxi-imino alcohol ligand are determined using reflectance and transmittance spectra. Analysis of the basis absorption spectra is also carried out to determine optical band gap (E-g) and Urbach parameter (E-o). The optical absorption studies reveal that the transition is direct with band gap energy values are calculated. The optical band gaps, film thickness and Urbach parameters are approximately found 3.9 - 4.0 eV, 1 mu m and the range of 0.210-0.657 eV, respectively.
