Refractometric sensing with plasmon resonances in dimer, trimer and quadrumer ensembles of gold nanoparticles

Year: 2024

Type: article

Abstract: \nWe studied by FDTD computer simulations the dependence of the surface plasmon resonances in linearly arranged gold nanospheres on incident light polarization, spheres number and diameter, and interparticle gap. The observed scattering spectra of large particles show a particularly interesting behaviour, with coupled plasmon resonances that can be either red or blue shifting with the modification of the interparticle gap. The sensitivity of the various observed coupled plasmon modes to refractive index variations is then evaluated.\n
