Onset of Intense Surface Enhanced Raman Scattering and Aggregation in the Au@Ag System

Figure 8

In this figure corrected SERS intensities are plotted against the corresponding aggregate extinction data (measured at 830 nm) for R6G (circles), MPY (squares), and MBA titrated with KCl (triangles). R6G and MBA are associated with the right -axis and MPY is associated with the left.
