• of up to 1012 [7]. This is possible thanks to the strong electromagnetic (EM) field amplification achieved with surface plasmon resonances, especially when the field is confined in nanometric metallic structures under the form of a localized surface plasmon resonance (LSPR) [8][9][10][11][12][13][14

• important characteristics of AuNRs is that as light interacts with them, localized surface plasmon resonance (LSPR) is excited and locally oscillates around the particle [1]. LSPRs are electromagnetic modes associated with the collective oscillations of the free electrons confined to the nanoscale size

• fabricated through layer-by-layer physical vapor deposition (PVD). The change in the peak position of the localized surface plasmon resonance (LSPR) was monitored as a function of time and gas concentration. The responses of the films were preferential towards H2, as observed from the results of exposing the

• observing the change in the position of the localized surface plasmon resonance (LSPR) peak. This work employs a layer-by-layer approach, meaning that the Au was first deposited and annealed to form nanoparticles and was then followed by the deposition and annealing of the YSZ capping layer.
