Size- and shape-dependent optical properties of Au NPs in ThMo arrangement.

Extinction spectra of ThMo nanopatterns with d=180 nm, a=100 nm and circular (A), square (B), and triangular (C) NPs. Trends of the LSPR peak wavelength versus the refractive index of the medium achieved for ThMo investigated with different minimum interparticle distance a and circular (D), square (E), and triangular (F) NPs. In (B) and (E), the spectral response obtained by numerical simulations is reported in grey color.
