Abstract

Two amorphous films, Cu_xO-W0₃ and V₂0₅-W0₃, are investgated Co determine electrochromism and their optical properties. The color and transmittance of the films can change continuously and reversibly. This multi-colored effect is due to sequential transfer of Cu²-Cu^l⁺ and W⁶⁺=== W⁵⁺ in Cu_x0W0₃ films and V⁴⁺ reversible processes occurring in V20₅-W0₃ films. Because of these optical properties, this type of films may be used for selectively transmitting windows or information display devices.
