Electrochromic Properties of Iron Oxide Thin Films Prepared by Chemical Vapor Deposition

Abstract
Iron oxide thin films were prepared by chemical vapor deposition. The source material was iron (III) acetylacetonate. The films were produced at a substrate temperature above 200°C. The films deposited at a substrate temperature above 300°C were polycrystalline . Reduction and oxidation of the amorphous films in a 0.3 M propylene carbonate solution caused desirable changes in optical absorption. Coulometry indicated that the coloration efficiency was 6.0 to .
