Optical And Electrical Studies Of Electrochromic Polycrystalline WO 3 And MoO 3 Thin Films Prepared By CVD

The electrical and optical properties of polycrystalline WO₃ and MoO₃, thin films prepared by Chemical Vapor Deposition were determined. The electrochromic characteristics of these films were investigated using protons as inserting ions. The influence of preparative conditions on optical, electrical and electrochromic properties is presented. An experimental study of optical spectra of colored or bleached WO₃ samples is shown and discussed using a free electron scattering model.
