摘要：
A palladium silver (Pd-Ag) film coated LPG for hydrogen sensing is represented in this paper. This hydrogen sensor is a LPG coated with Pd-Ag film, and the thick of the film is about 70nm. When the sensor is exposed to hydrogen, the refractive index of Pd-Ag will change, and it will cause the shift of the resonance wavelength of LPG. Therefore, the concentration of hydrogen can be monitored by measuring the shift of resonance wavelength of LPG. The preliminary experiment shows that Pd-Ag film coated LPG has an obvious response to 3 similar to 4% hydrogen, with a response time of a few minutes at 4% hydrogen.
