Description

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 VO_x 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.
