(a–c) correspond to the reflectance, transmittance, and absorbance, respectively, of \(\alpha\)-\(\hbox {MoO}_{{3}}\) for x-polarized incident light as a function of thickness and frequency. (d–f) represent the reflectance, transmittance, and absorbance, respectively, of \(\alpha\)-\(\hbox {MoO}_{{3}}\) for y-polarized incident light as a function of thickness and frequency. The scatter plots in absorption color plots correspond to Fabry Perot modes of \(\alpha\)-\(\hbox {MoO}_{{3}}\) film.
