Surface-Enhanced Raman Scattering of Indigo on a Stable Silver Foil Substrate Prepared by a Nitric Acid Etching Method

A chemical etching method with HNO3-prepared silver foils was used for a Raman study. These foils were found to exhibit a strong SERS effect. An SEM image clearly shows that spherical particles exist in an oxidized state, with diameters in the range of 200 nm for oxidized silver. SERS spectrum of In...
