•Single-precursor was used for the APCVD of VO2 coatings.•VO2 properties were strongly dependent on the N2 flow rate through the bubbler.•VO2 presented thermochromic performance despite the amorphous character.
This work reports the growth of thermochromic amorphous vanadium dioxide coatings on SnO2-precoated glass substrates by atmospheric pressure chemical vapor deposition using vanadyl (V) triisopropoxide as single-precursor at 450 °C. The best reversible transition behavior was at 65.5 °C as derived from the transmittance–temperature measurements. This finding is discussed in terms of variations in microstructure occurring during the different nitrogen flow rate studies. We show that the thermochromic behavior of the oxides is determined by the presence of well-defined monoclinic vanadium dioxide.
