Abstract

Disclosed herein are porous electrochromic niobium oxide films comprising a plurality of niobium oxide nanocrystals, wherein the plurality of niobium oxide nanocrystals comprise niobium oxide having a formula of NbOx where x represents the average Nb:O ratio in the niobium oxide and where x is from 2 to 2.6. Also disclosed herein are methods of making the porous electrochromic niobium oxide films, methods of use of the porous electrochromic niobium oxide films, and devices comprising the porous electrochromic niobium oxide films.
