Abstract
A novel hydrogen sensing device consisting of palladium thin film was prepared on a glass substrate by radio-frequency magnetron sputtering. When the sample was exposed to hydrogen, the optical transmittance in creased and saturated at a constant value. The transmittance returned to its initial value by exposing the sample to dry air. Its optical tr ansmittance was found to depend on the hydrogen concentration in the a mbient atmosphere. This phenomenon is proposed to be utilized as a new type of hydrogen sensor.
