Optical properties of the films of vanadium and tungsten oxides in a gas atmosphere, containing hydrogen, have been investigated. Films have been synthesized by electrodeposition and chemical deposition from aqueous solutions. Vanadium (V) oxide films and tungsten (VI) oxide films with a platinum catalyst reversibly change their color being exposed to hydrogen. The present work show promising use for such films as sensitive optical elements for gas sensors
