Abstract
In this study, we created a multilayer SPR hydrogen sensor that is primarily based on an Ag-nd or Au-nd heterogeneous metal nanolayer. To characterize the response of the suggested structure, we used the Matlab program and the transfer matrix method (TMatrix) in this investigation. We developed a set of sensors (n1/Ag-nd/Pd Or n1/Aund/Pd) with varying densities of metal nanoparticles N = 400[1/µm3 ], 600[1/µm3 ], 800[1/µm3 ], and 1000 [1/µm3 ], respectively, to verify the sensor's performance. They are assessed using a number of conventional standards, including sensitivity and minimum reflectance (Rmin). The sensor with Ag-nd layer and N = 1000 [1/µm3 ] was found to attain the lowest Rmin of 0.04 and the highest sensitivity of S = 7.99[nm] with a maximum resonance wavelength shift of 2.4 [nm]. The suggested SPR hydrogen sensor may detect changes in palladium (Pd)'s optical characteristics and, consequently, leaks of hydrogen gas, according to simulation data.
