Optical hydrogen sensing with high-Q guided-mode resonance of Al2O3/WO3/Pd nanostructure

Optical hydrogen sensing with high-Q guided-mode resonance of Al2O3/WO3/Pd nanostructure

Abstract Nanostructure based on a dielectric grating (Al2O3), gasochromic oxide (WO3) and catalyst (Pd) is proposed as a hydrogen sensor working at the room temperature. In the fabricated structure, the Pd catalyst film was as thin as 1 nm that allowed a significant decrease in the optical absorptio...
