The effect of oxygen-containing reagents on the crystal morphology and orientation in tungsten oxide thin films deposited via atmospheric pressure chemical vapour deposition (APCVD) on glass substrates
The effect of oxygen-containing reagents on the crystal morphology and orientation in tungsten oxide thin films deposited via atmospheric pressure chemical vapour deposition (APCVD) on glass substrates
Thin films of monoclinic WO(3) and WO(3-x) have been synthesized by atmospheric pressure chemical vapour deposition from WCl(6) and three oxygen containing precursors; water, ethanol and ethanoic anhydride. A wide variation in the colour, crystal morphology and preferred orientation of the films was observed, depending on the chosen oxygen source. In particular contrast were the films formed from WCl(6) and ethanol, which were blue and had needle-like crystallites, and those formed from WCl(6) and water, which were yellow and had hexagonal shaped crystallites. Studies were also undertaken to form films from WCl(6), ethanol and water simultaneously, in which the ratio of ethanol to water was varied, and this led to films in which the crystal morphology and orientation could be controlled.

Abstract
Thin films of monoclinic WO(3) and WO(3-x) have been synthesized by atmospheric pressure chemical vapour deposition from WCl(6) and three oxygen containing precursors; water, ethanol and ethanoic anhydride. A wide variation in the colour, crystal morphology and preferred orientation of the films was observed, depending on the chosen oxygen source. In particular contrast were the films formed from WCl(6) and ethanol, which were blue and had needle-like crystallites, and those formed from WCl(6) and water, which were yellow and had hexagonal shaped crystallites. Studies were also undertaken to form films from WCl(6), ethanol and water simultaneously, in which the ratio of ethanol to water was varied, and this led to films in which the crystal morphology and orientation could be controlled.
