Abstract
We report a scalable manufacturing approach to produce nano-porous metal oxide films and the dopant variants using a block-copolymer template combined with a sol–gel solution processing approach. The refractive index of the film can be tailored to 1.2–2.4 by 3D nanostructuring in the sub-wavelength regime at scales of 20 nm or less. Based on this approach, this paper reports the synthesis of nanoporous palladium (Pd)-doped titanium dioxide (TiO2) film with refractive index matching the optical fiber material, and its importance on D-shaped fiber Bragg grating for hydrogen sensing at extremely high temperature up to 700°C. The sensor is based on evanescent field interaction in hydrogen-sensitive cladding. The flat side of D-shaped fiber grating was etched to remove a residual 4 μm cladding material, and thermally stabilized for high-temperature requirements. The peak intensity change of the fiber Bragg wavelength was observed with different hydrogen concentrations from 0.25 vol.% H2/N2 to 5 vol.% H2/N2. The experimental result shows that the sensor’s hydrogen response is reversible and fast. The response time of the hydrogen sensor is <8 s.
