[The influence of KCl on SERS of fuchsin basic in silver colloids].
Surface enhanced Raman scattering (SERS) spectra of fuchsin basic (FB) in silver colloids were measured. The influence of KCl on the SERS of FB was studied systematically with different excitation wavelengths (476.5, 488.0, 514.5, 632.8nm). The dependence of the relative SERS intensity of the 1366cm(-1) and 242cm(-1) bands of FB on KCl mole value at different excitation wavelengths were given. The SERS spectra of FB at 514.5nm and 632.8nm wavelength excitations were very different, and the relative intensity of 242cm(-1) to 1366cm(-1) SERS spectra was changed.
