Figure 7

SERS spectra recorded from Ag cubes with four different edge lengths: 57 nm, 82 nm, 125 nm, and 170 nm (from bottom to top in the plot) under two laser polarization directions: (A) along an edge and (B) along a face diagonal. The scale bars in the insets correspond to 100 nm and are applied to all the images. cps=counts per second.
