We have investigated the variations in the transmission spectra of nanodiscs as well as metal hole array plasmonic structures as a result of the hydrogen adsorption–desorption processes. The structures have been shown to be a viable platform for all-optical hydrogen sensing in the infrared. In cases of both nanodisc and metal hole arrays, upon exposure to hydrogen, a redshift of the plasmon resonance band was observed. Response time as well as the magnitude of the spectral shift was similar for both plasmonic structure types.
