摘　　要：测量了银胶中碱性品红的表面增强拉曼散射（ＳＥＲＳ）光谱。系统考察了不同波长光激发下ＫＣｌ对碱性品红ＳＥＲＳ光谱的影响，给出了不同波长光激发下碱性品红的１３６６ｃｍ－１和２４２ｃｍ－１峰相对强度随ＫＣｌ量（或浓度对数值）的变化曲线。５１４．５ｎｍ和６３２．８ｎｍ光激发的碱性品红的ＳＥＲＳ谱有明显差异。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.
