Cold Atmospheric-Pressure Plasma-Assisted Aerosol Synthesized WOxCyNz1Clz2 Films for Energy Saving Dual-Band Electrochromic Devices

Article Preview

Abstract:

The facile, fast and cost effective atmospheric-pressure cold plasma-assisted aerosol deposition (APCP-AAD) method is investigated to synthesize dual-band electrochromic (DB-EC) chloro-nitro-organo-tungsten oxide (WOxCyNz1Clz2) films with independently selective visible (VIS) and near-infrared (NIR) light. DB-EC WOxCyNz1Clz2 film can be switched by three changed EC modes including bright, cool and dark states by adjusting various electrical potentials to correspond the favorites and comfort of construction residents and reduce energy consumption for lighting and heat management. High optical modulation in VIS light ΔTbright to dark, 600 nm up to 67.4% and in NIR light ΔTbright to dark, 1,000 nm up to 72.4%, and fast response times in coloring duration up to 5.0 s and in bleaching duration up to 1.2 s.
