Abstract: The optical constants and thickness of TiО$_2$–MnO$_2$ films (with MnO$_2$ concentration of 0, 1, and 5%) prepared by electron-beam evaporation are determined. A considerable dependence of the optical properties of thin TiO$_2$ films on the manganese concentration is observed. It is found that thin films are indirect gap semiconductors with gap width $E_g$ = 3.43 eV (TiO$_2$), 2.89 eV (TiО$_2$–MnO$_2$ (1%)), and 2.73 eV (TiО$_2$–MnO$_2$ (5%)).
