Abstract
Electrochromic properties of the V2O5 thin films prepared from a spinnable organic vanadium solution were investigated. The films heat‐treated at 400 °C showed clear two‐step electrochromism, deep blue⇄green⇄yellow, with its response time for obtaining ΔOD=0.5 being ∼2 s. The yellow and green colors showed good memory effects for more than 20 h, while the blue one was considerably degraded within 10 h.Keywords
