Research Abstract

In this study, Pt-WO_3 thin films were prepared on glass substrates using a sol-gel process. Amorphous and crystalline WO_3 were easily obtained by changing the heat-treatment temperature. The optical absorbance of the film was dependent on the H_2 gas concentration in the range from 0.1 to 5% and the relationship between them was linear. The relationship between the electrical conductivity and hydrogen gas concentration in the range from 100 to 10000ppm was also linear. From these results, Pt-WO_3 thin film prepared by sol-gel process is expected to apply for hydrogen gas sensor.
