Figure 8. — Surface enhanced Raman scattering (SERS) spectra of crystal violet (CV) and rhodamine 6G (R6G) molecules on wrinkled nanoporous gold (NPG) films. (a) Comparison of SERS intensity between wrinkled and as-prepared NPGs with different nanopore sizes; (b) SERS spectra from wrinkled NPG with different nanopore sizes of 12 nm(w-NPG12), 26 nm (w-NPG26), and 38 nm (w-NPG38); (c) variation of SERS spectra of CV on w-NPG26 at different sites along a wrinkle ridge; (d) variation of SERS spectra of R6G on w-NPG26 at different sites along a wrinkle ridge. The excitation wavelength is 632.8 nm for CV and 514.5 nm for R6G. Reprinted with permission from [86]. Copyright 2011, American Chemical Society.
