Abstract
- Dispersion theory for refractive index and extinction coefficient of vanadium dioxide thin film is studied, and its temperature-dependence dispersion formula of optical constants is presented by numerical fitting with Sellmeier dispersion model. The optical transmittance and reflectance at different temperature and wavelength is calculated using film matrix theory. Vanadium dioxide thin films with different thickness are deposited by magnetron sputtering on glass, sapphire and silicon dioxide substrates, and the optical transmittance and reflectivity of the films are measured, and the experiment curve agrees well with that of simulation.
