Abstract
An improved electrochromic layer containing M.sub.X WO.sub.Y, M.sub.X NiO.sub.Y, M.sub.X VO.sub.Y, M.sub.X MoO.sub.Y, M.sub.XCrO.sub.Y, M.sub.X RuO.sub.Y, M.sub.X IrO.sub.Y, or M.sub.X TiO.sub.Y, where M is selected from the group consisting of alkali metals and alkaline earth metals, X is less than 0.06 and Y is in the range from 2 to 3.2. The layer contains the alkali metal or alkaline earth metal when the electrochromic layer is formed.
