a SERS spectrum of RB with different substrates. RB (10−7 M). b SERS spectrum of RB with a gradient concentration. c The relationship between the Raman intensity and logarithmic RB concentrations for the bands at 1647 and 1260 cm−1. Log-log plot of the Raman intensity versus the concentration of RB is shown in the inset. d Six SERS spectra collected randomly in the scanned area on the substrate. RB (10−9 M)
