ELECTROCHROMIC, OXYGEN DEFICIENT METAL OXIDE FILMS PROVIDED BY PYROLYTIC DEPOSITION

摘要

This invention is directed to electrochomic devices wherein a layer of cathodic electrochomic material comprising non-stoichiometric, oxygen deficient metal oxides is provided by pyrolytic deposition techniques. The pyrolytic deposition is of a compound comprising a powdered metal compound and a reducing agent or liquid composition and a reducing agent. The pyrolytic deposition can also be accomplished by a powdered composition or a liquid composition dispersed in a carrier gas.
