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。２４２ｃｍ－１峰与其他峰的相对强度发生变化
The surface enhanced Raman scattering (SERS) spectra of basic fuchsine in silver glue were measured. The influence of KCl on basic fuchsia SERS spectra under different excitation light wavelengths was systematically investigated. The relative intensities of 1346cm-1 and 242cm-1 peaks of basic magenta with different wavelengths of light excited by KCl (or logarithm of concentration ) Of the curve. The SERS spectra of basic fuchsin excited by 514.5nm and 632.8nm were significantly different. The relative intensities of the 242 cm-1 peak and other peaks changed
