Thermochromic vanadium dioxide (VO2) films have attracted enormous attention in the past decade owing to their high potential active optical filters, sensors, anevices. VO2 patterned at micro- and nanoscale is an evident route toward next-generation devices justifying need for scalable, straightforward, high-performing nanofabrication technologies being easily applied this material. Herein, precise nondestructive femtosecond laser nanopatterning of both direct ablation plasmon-assisted self-organization regimes reported under ambient conditions. Our studies unveil formation spatially uniform subwavelength nanogratings (or laser-induced periodic surface structures) with a periodicity around 100 nm through excitation interference plasmons film upon its multipulse irradiation. Plasmon-assisted nanotexturing preserves pristine composition film, strongly modulating properties enhanced visible-range transmittance thermochromic anisotropy near-IR spectral range. Overall, our study not only sheds light onto origin laser-driven films, but also unveils huge scalable fs-laser patterning creating novel optoelectronic sensing based on optically anisotropic nanotextured films.
