This paper reports the atmospheric pressure chemical vapor deposition of vanadium oxide coatings using vanadyl (IV) acetylacetonate at 500 oC. The as-grown samples for 0.8 L min-1 O2 flow rate showed an (022)-oriented single vanadium dioxide monoclinic phase of low crystallinity. The narrowest hysteresis width is observed for the particular flow rate indicating a dependency on the shape of the grown crystallites. Regarding the difference in transmittance is determined by the enhanced presence of short- and long-range bond ordering of the samples. (© 2015 WILEY-VCH Verlag GmbH & Co.
