Abstract
This specification discloses reduced tungsten oxide electrochromic material, useful in an electrochromic device, having excellent electrochromic properties. The oxidation number of the tungsten of the material as deposited on a support of the device in a stable bleached condition is, on average, between +5.99 and +5.90. The material may be made by reducing fully oxidized tungsten oxide by a reducing agent. The reducing agent may be a metal or a metal oxide.
