Vanadium dioxide is widely explored as a viable material for switching applications and a robust progress has been achieved on laboratory-scale. To realise its commercialisation, industrially-viable synthetic techniques are highly required. Ultrasonic nebulised spray pyrolysis of aqueous combustion mixture (UNSPACM) is a simple, low-cost and scalable technique which offers high quality films for various energy applications. Herein, we report synthesis, characterization and influence of Ce–W co-doping on phase transition temperature of VO 2 (M1) thin films deposited on quartz substrates at 350 °C by this technique. The phase was verified by x-ray diffraction and Raman spectroscopic studies. FTIR studies at 2.5 µ m to 14 µ m IR frequencies showed 63% reversible reflectance change of the films from low reflectivity below 60 °C to high reflectivity above 60 °C. Electrical resistance measurements on the thin films showed a first order transition with resistance c...
