| 摘要: |
Transmission measurements have been used to investigate the optical properties of polyvinylpyrrolidone（PVP）∕ZrO2 films synthesized by the solgel route. The optical constants of PVP∕ZrO2 films deposited on quartz substrates were determined by fitting transmission spectra in the wavelength range of
200–800 nm with the Tauc–Lorentz and Cody–Lorentz physical models. Combined with Urbach tail, both models give a good description of transmission data and reveal that refractive index of film slightly decreases with increasing PVP mass fraction. X-ray reflectivity (XRR) measurements were also performed
on PVP∕ZrO2 films to complement the thicknesses. The value of film thickness, including interface information from transmission spectra, is consistent with that result obtained from XRR,indicating that fitting transmission spectrum is a high reliable optical characterization. |
