TLDR
In this paper, the electrical properties of tungsten-molybdenum oxide (W1y MoyO3) thin films were investigated and the films were deposited on indium tin oxide covered glass by reactive DC sputtering from tungstein and molybbenium targets.Abstract:
Electrochromic (EC) properties of tungsten-molybdenum oxide (W1-y MoyO3) thin films were investigated The films were deposited on indium tin oxide covered glass by reactive DC sputtering from tungsten and molybdenum targets Elemental compositions of the W1-y MoyO3 films were determined by Rutherford back scattering Voltammetric cycling was performed in an electrolyte of 1 M LiClO4 in propylene carbonate An increase in molybdenum content in the EC films caused both a shift towards higher energies and a lowering of the maximum of the optical absorption band, as compared with WO3 EC films Durability under electrochemical cycling was diminished for W1-y MoyO3 EC filmsread more
