N2 - The relation between hydrogen and gasochromic properties were investigated by measuring simultaneously hydrogen concentration depth profiles and optical absorption in tungsten oxide films prepared by RF magnetron sputtering and pulsed laser deposition. A large amount of hydrogen was contained in the amorphous WO3 films prepared by the both methods. The excellent gasochromic properties were found in amorphous HxWO3 films with the maximum value of x about 0.8, while poorer coloration was observed in the films with less hydrogen. Under hydrogen exposure, hydrogen concentration increased with increasing the optical absorption in the wavelength of 600 - 1000 nm.
