Method for preparing surface for obtaining surface-enhanced Raman scattering spectra of organic compounds

摘要

A surface-enhanced Raman scattering surface is prepared by anodizing an aluminum or aluminum alloy substrate with reversed polarity current to form pores of anodized oxide on the substrate, and electrodepositing silver or copper into the pores of the anodic oxide film to form needle-shaped metal particles in the pores of the anodic oxide film.
