Thermochromic Di vanadium pentaoxide (V2O5) coatings displaying a variety of colours were synthesised. Tuning of thermochromic behaviour was achieved via a controlled oxidative annealing under ambient air of the as-grown VOx films. Adjusting the oxygen deficiency in V2O5, allows tuning the colour of the films and as a consequence its thermochromic behaviour. Non oxygen deficient V2O5 did not feature any measurable thermochromism
