(a) Temperature profiles of the Ti4O7 films, deposited at different Ts (the solar simulator was lighted on for 900 s and then shutdown). The maximum temperatures (Tmax) reached by the samples following their insolation are indicated in light blue box; (b) Thermal images of the Ti4O7/Ti sample, coated at Ts = 500 °C, taken at different elapsing times (from t = 0 to 900 s); The actual size of the samples is 1ʹʹ x 1ʹʹ; (c) External photothermal conversion efficiency (ηext) of the Ti4O7 films as a function of their Ts.
