We investigated the electrochromic properties of tungsten-nickel-titanium oxide (W1-x-yNixTiyO3) thin films. Special emphasis was put on W0.83-xNixTi0.17O3 since this composition gave the highest electrochemical durability. The films were deposited onto indium-tin oxide coated glass by reactive DC magnetron sputtering, and cyclic voltammetry as well as optical transmittance measurements were performed in an electrolyte of 1 M LiClO4 in propylene carbonate. The potential window was chosen so as to cause rapid degradation of the samples. Elemental compositions were obtained by Rutherford backscattering spectroscopy and structural information by X-ray diffraction. We verified that the titanium additive improved the electrochemical durability of tungsten-oxide-based films and also documented that a further addition of nickel was unable to enhance the EC performance to any significant degree.
