Abstract

Flake-like VO₂ (M) has been successfully synthesized by annealing plate-like (NH₄)_0.6V₂O₅ in vacuum and its thermochromicity was investigated. Preparation conditions such as temperature and vacuum degree have been varied to obtain the pure phase. The formation mechanism from ammonium vanadium bronze to VO₂ (M) has been explored. The flake-like VO₂ (M) shows an excellent thermochromicity; the infrared modulation at 2500 nm was up to 56.6% with a 30% visible transmittance which will be beneficial for smart windows, smart curtains or other applications.
