| Research Abstract |
Effects of gamma-ray, electron and ion irradiation on hydrogen gasochromic properties of transition metal oxide (tungsten trioxide, molybdenum trioxide etc.) films coated with a noble metal catalyst (platinum, palladium) were investigated for development of hydrogen sensors to operate under radiation environment. The results indicate that hydrogen gasochromism of the crystalline oriented films of tungsten trioxide coated with platinum (Pt/WO_3) is unaffected by gamma-ray irradiation. Successfully realized optical hydrogen sensors made of the Pt/WO_3 films demonstrate for operate to under gamma-ray irradiation conditions.
