Title: Methods for producing electrochromic films by low temperature condensation of polyoxometalates

Abstract

Described are electrochromic films produced by low temperature condensation of polyoxometalates and applications thereof. A method of producing an electrochromic film includes depositing a polyoxometalate (POM) solution on a substrate to form a POM film. The POM solution includes anionic POM clusters and counter ions, and may be doped with near-infrared plasmonic nanocrystals. The film is chemically cured using an acid to condense the POM clusters within the POM film. Another method of producing an electrochromic film includes electrochemical deposition and condensation of POM clusters.
