Synthesis and Functional Properties of Vanadium Oxides: V₂O₃, VO₂, and V₂O₅ Deposited on Glass by Aerosol‐Assisted CVD

Abstract

Thin films of vanadium oxides were deposited on glass by aerosol-assisted (AA) CVD from vanadium(III) acetylacetonate and vanadyl(IV) acetylacetonate. The vanadium precursor, solvent, and carrier gas flow rate determined the phase of vanadium oxide formed (V 2 O 3 , VO 2 , or V 2 O 5 ). Films were characterized using various analytical techniques. VO 2 films were analyzed at various temperatures to study their thermochromic behavior. The V 2 O 3 reflectance-transmission plots showed a cross-over (ideal behavior for a solar-control mirror).

Selective oxidation of H2S to sulfur over vanadia supported on mesoporous zirconium phosphate heterostructure

“…Moreover, we must indicate the absence of VO2 crystals in used catalysts, which is characterized by the presence of a band at 614 cm -1 [33].…”

Thermochromic Coatings for Intelligent Architectural Glazing

“…Four precursor systems have received the most attention in the preparation of thin films of tungsten doped vanadium (IV) oxide via APCVD [62][63][64]. Some work has been conducted using aerosol assisted chemical vapour deposition (AACVD) to produce thin films of tungsten or niobium doped vanadium (IV) oxide [68,69,71].…”

“…It was shown that experimental parameters such as the vanadium precursor, the nature of the solvent and the carrier gas flow rate affected the nature of the deposited phase [68]. The optimised conditions subsequently used to deposit doped VO 2 are listed in table 3.…”

Interdependence of Structure, Morphology, and Phase Transitions in CVD Grown VO2 and V2O3 Nanostructures

“…[28][29][30] Nevertheless, the deposition of monoclinic VO2 (M1) is only possible in a narrow temperature window around 550 °C and usually only a limited control over surface morphology has been observed. [26,31] Nanostructured surface morphologies play an important role in the thermochromic performance of VO2 films in terms of phase transition temperature and visible light transmission. [32][33][34] Recently, Binions et al reported the use of an electric field in an aerosol-assisted and atmospheric pressure CVD and demonstrated a reduction in the crystallite size and phase transition temperature.…”
