Iron oxide thin films were prepared by chemical vapor deposition. The source material was iron (III) acetylacetonate. The Fe{sub 2}O{sub 3} films were produced at a substrate temperature above 200 C. The films deposited at a substrate temperature above 300 C were polycrystalline {beta}-Fe{sub 2}O{sub 3}. Reduction and oxidation of the amorphous films in a 0.3 M LiClO{sub 4} propylene carbonate solution caused desirable changes in optical absorption. Coulometry indicated that the coloration efficiency was 6.0 to 6.5 cm{sup 2}/C.
