Monoclinic oxygen-deficient tungsten oxide nanowires for dynamic and independent control of near-infrared and visible light transmittance

Abstract

The transmittance of near-infrared (NIR) and visible (VIS) light spectral regions can be dynamically and independently controlled using a single-component material – monoclinic oxygen-deficient tungsten oxide nanowires, without the need for compositing with other electrochromic materials. A localized surface plasmon resonance and phase-transition assisted mechanism and bandgap transition electrochromism are individually responsible for the modulation of the NIR and VIS light transmissions.
