Figure 5
Simulated light extinction cross-section spectra for semi-ellipsoid- and parallelepiped-shaped Au nanoparticles on glass substrates. Insets show top view AFM images for random gold NSA samples. Numbers correspond to samples R1, R4, and R6, respectively. Effective geometrical parameters of Au nanoparticles used in FDTD modelling are the same for semi-ellipsoid and parallelepiped shapes and correspond to the data presented in Table 1 for samples R1, R4, and R6, respectively.
