Solution-phase SERS spectra of the as-prepared Ag nanocubes with five different edge lengths as labeled on the plot. Band assignments for PVP are as follows: C-C stretch (689 cm−1), pyrrolidone ring torsion (749 cm−1), pyrrolidone ring breathing mode (841 and 862 cm−1), CH2 ring rocking mode (936 cm−1), and backbone CH2 deformation (1004 cm−1). cps=counts per second.
