ABSTRACT:
This specification is directed to electrochromic optical shutter (10) in which an electrochromic material (12), an ion conductor (14), and a counter electrode (16), in that order, are sandwiched between visibly transparent electrodes (18-18). The shutter is improved by forming the counter electrode from a nickel oxide applied to, as a base therefor, either the ion conductor or one of the transparent electrodes. The material is applied by a pyrolytic spray process in which a solution containing nickel as a pyrolyzable organic salt dissolved in an organic medium is sprayed on the base. The base has been previously heated to a temperature sufficient to pyrolyze the sprayed material and form a nickel oxide counter electrode layer.
