CONCENTRATION-DEPENDENCE OF SURFACE-ENHANCED RAMAN-SCATTERING FOR ORGANIC DISULFIDE ADSORBED ON METALS FROM SOLUTIONS

The concentration dependence of surface-enhanced Raman scattering (SERS) of adsorbed benzyl disulfide and phenol disulfide on surfaces of silver and gold has been investigated. It has been found that the spectral qualities are inversely proportional to the concentration of the applied solutions. Excellent SERS spectral enhancement and perpendicular orientation could be achieved for the sample adsorbed from a 0.0001M solution rather than that from a 0.001M solution. This phenomenon was termed as the ''dilution effect'' on SERS spectra.
