| 摘 要： | 采用溶液电镀方法在多孔硅表面制备纳米尺寸的银颗粒，测量了不同镀银多孔硅表面吸附的ＲｈＢ染料分子以及固态的ＲｈＢ染料的Ｒａｍａｎ散射谱。在相同的激发强度下，固态ＲｈＢ染料的Ｒａｍａｎ散射最弱，而镀银的多孔硅表面具有明显的增强效果（～１０＾４）。

| Abstract: | The viborational modes of RhB dye molecule adsorbed on the silver particles prepared on porous silicon electrodeposition were studied by Surface enhanced Raman Scattering method. The experimental results showed the enhancement are associated with the electrodeposition time when the depositing condition remains invariable. |
