Files include the data presented in the manuscript entitled: "Coloration mechanism in gasochromic thin films through the analysis of a complex refractive index" by Mazur et al. (https://doi.org/10.1364/AO.474012)
Fig. 1 presents theoretical characteristics of n^2-1 versus hv^2 and refractive index versus light wavelength. The dispersion of presented curves was calculated assuming variation of the resonance energy of the oscillator Eo and Eg for WO3 and WO2, respectively. Data was calculated with the aid of SCOUT software.
Fig. 2 presents theoretical characteristics of extinction coefficient (k) versus wavelength (l) simulated for different concentrations of electrical charge carriers. Data was calculated using SCOUT software.
Fig. 3 presents simulated theoretical transmission curves: WO3 with electron concentration of 10^16 cm^3, and WO2 with electron concentration of 5*10^18 cm^3. Data was calculated using SCOUT software.
Fig. 6 presents transmission characteristics of the Pt=WO3 thin film deposited on fused silica glass, recorded in pure air and under 3.5% hydrogen. Measurements were done using experimental setup for gasochromic research, including, among others, Ocean Optics QE65000 spectrophotometer and DH-BAL 2000 light source.
FIg. 7 presents Optical dispersion spectra of (a) real and (b) imaginary parts of the refraction index calculated from experimental transmission spectra for WO3 thin films investigated in pure air and under 3.5% hydrogen. Data was calculated using SCOUT software.
Fig. 8 presents Characteristics of (a) n^2-1 versus hv^2 and (b) k versus lambda with linear approximation according to discussed Wemple–DiDomenico and Drude models for investigatedWO3 thin film. Data was calculated using OriginLab software.
