Figure Lengend Snippet: Electric field distribution ( E / E 0 ) of the different AuNS sizes at 680 and 808 nm, the two wavelengths used in the photothermal response section. Electric field distribution was determined from theoretical calculation based on FEM using COMSOL Multiphysics. Aggregates of 5 AuNSs have been considered with different interparticle gaps (0.75, 1 and 2 nm). The colour scale corresponds to the electrical field intensity. Hot spots appear within interparticle spacing and their field intensity depends on the AuNS size and gap distance. Scale bars correspond to the diameter of each AuNS.
Article Snippet: In this study, the plasmonic behavior of gold nanospheres (AuNSs) of different sizes has been investigated by creating a 3D model based on the finite element method in COMSOL Multiphysics.
