Abstract:Surface enhanced Raman spectrometry (SERS) of copperphthalocyanine (CuPc) in silver hydrosol is reported. The solvent effect on the Raman activity of the adsorbate is discussed in terms of co-adsorption and replacement kinetics of the solvent molecules at the silver surface. It is shown that the quality of the SER spectra can be improved by optimizing the solvent for the adsorbate under study.
