Özet

In this study, optical properties of Cu-doped Zinc-Borate glassy thin films (GTFZs) were investigated. The glassy thin films of bulk glasses were grown onto SiO(2) substrates with argon gas plasma under vacuum with RF sputtering technique. As a result of XRD analysis of obtained glassy thin films, they are observed to have amorphous structure. From absorbance and transmission data obtained from Uv-Vis spectra of thin films, optical band gaps for direct and indirect transitions and also Urbach energies were calculated. Not only the fundamental absorption edge and cut-off wavelength shift towards red with the increase in V(2)O(5) content, but also ZnO narrows the optical band gaps.
