Abstract: We measured the surface enhanced Raman spectra (SERS) of the malachite green on silver film deposited on optic polished quartz slides by using chemical method. The effects of the excitation wavelength, electrolyte (NaCl) concentration and pHon the SERS were investigated. The results indicate that the relative intensities for some bands depended upon the excitation wavelength; Inorganic anion(Cl-) not only enhanced the SERSintensities, but also changed the relative intensities of the SERSsensitive bands; The SERS intensities increased with pHfrom 1-7 and reached maximum value at pH=7, and then decreased. The possible origin for the phenomena was discussed.
