Abstract
An electrodeposition smart window exhibits superior light blocking efficiency compared to conventional smart windows, thereby enabling a significant change in light transmittance even with a small current, and is thus highly advantageous in terms of energy efficiency.
Claims15
An electrodeposition smart window, comprising:
- a substrate, and
- an electrochromic layer formed on the substrate;
- wherein, when a voltage is applied, the electrochromic layer comprises a metal nanoparticle array on the substrate, and
- wherein, for light in a wavelength range of 400 nm to 2500 nm, an effective refractive index of the metal nanoparticle array is greater than a magnitude (i.e., an absolute value) of a refractive index of a bulk metal of a same kind as metal nanoparticles for at least a specific wavelength range.
