Figure 4:

Extinction spectra of a periodic nanopattern based on nanoprisms with d=180 nm and a=100 nm (A).

Trends of the LSPR peak wavelength versus the refractive index of the medium achieved for the nanoprisms array with a=50 nm and a=100 nm (B). SEM image of the nanoprisms pattern with a=100 nm (C).
