ABSTRACT:
Describes an electrochromically active iridium oxide film of iridium, oxygen and nitrogen, wherein the ratio of atomic oxygen to iridium is from 3.2:1 to 3.4:1 and the amount of nitrogen in the film is from 11 to 13 atomic percent. Describes also an electrochromic article, e.g., a plastic article such as a plastic lens, in which the aforedescribed iridium oxide film is paired with a cathodically coloring electrochromic film, such as tungsten oxide.
