Abstract

The ultrahigh transparent VO₂ films with surface nanoparticles had been prepared by combining the high power impulse magnetron sputtering (HiPIMS) with the post-annealing. The single-sided VO₂ thin film with an ultrahigh luminous transmittance (T_lum) of 82.9% exhibited a transparent vision with solar modulation ability (ΔT_sol) of 6.1%, and the double-sided VO₂ thin film provided an excellent ΔT_sol of 9.3% while T_lum maintained at 70.6%. The size of VO₂ nanoparticles was effectively controlled by adjusting the oxygen flow rates, which can broaden the bandgap and regulate the localized surface plasmon resonance to balanced T_lum and ΔT_sol. The propound surface engineering approaches symbolize a facile and cost-effective strategy to improve thermochromic characteristics, which could facilitate the deployment of VO₂ film in smart windows and windshields of vehicles.
