Infrared optical properties modulation of VO₂ thin film fabricated by ultrafast pulsed laser deposition for thermochromic smart window applications.

ABSTRACT: Over the years, vanadium dioxide, (VO₂(M1)), has been extensively utilised to fabricate thermochromic thin films with the focus on using external stimuli, such as heat, to modulate the visible through near-infrared transmittance for energy efficiency of buildings and indoor comfort. It is thus valuable to extend the study of thermochromic materials into the mid-infrared (MIR) wavelengths for applications such as smart radiative devices. On top of this, there are numerous challenges with synthesising pure VO₂ (M1) thin films, as most fabrication techniques require the post-annealing of a deposited thin film to convert amorphous VO₂ into a crystalline phase. Here, we present a direct method to fabricate thicker VO₂(M1) thin films onto hot silica su
