Abstract :
A high-temperature fiber optical hydrogen sensor is demonstrated. The sensor is based on single-crystal sapphire fiber coated with nanostractured Pd-doped TiO2 thin film. The sensitivity of the sensor was evaluated for hydrogen concentrations varying from 0.02 % to 3% at temperature up to 800°C.
