Optical constants and polarimetric properties of ТіО2–MnO2 thin films

Abstract Optical constants of ТіО2–MnO2 (MnO2 content: 0%, 1%, 5%, 10%) thin films prepared by the electron-beam evaporation technique were determined using the envelope method. The optical properties of the TiO2–MnO2 thin films were strongly dependent on the MnO2 content. The TiO2–MnO2 thin films were established to be indirect band semiconductors with the band gap energies Eg: 3.43 eV (TiO2), 2.89 eV (TiO2–MnO2 (1%)) and 2.73 eV (TiO2–MnO2 (5%)). The polarimetric properties of the TiO2–MnO2 thin films were also investigated.
