| 摘 要： | 我们采用多孔硅和多孔硅银淀积表面作为衬底研究了ＲｈＢ染料分子的表面增强Ｒａ ｍａｎ散射。在多孔硅表面，ＲｈＢ染料分子的Ｒａｍａｎ散射有大约１０倍的表面增强效果；而在多孔硅的银淀积表面，表现出超过１０４表面增强。通过多孔硅表面银颗粒对ＲｈＢ染料分子荧光的抑制和对Ｒａｍａｎ散射的表面增强，我们获得了谱峰清晰的ＲｈＢ染料分子Ｒａｍａｎ散射谱

Surface Enhanced Raman Spectroscopy of RhB Dye Molecular Adsorbed on Silver Particles Deposited on Porous Silicon |

| Abstract: | The vibrational modes of RhB dye molecule adsorbed on the silver particles deposited on porous silicon electrodeposition were studied by Surface Enhanced Raman Scattering method. Raman scattering of RhB dye is enhanced by a factor of 10 when it is adsorbed onto porous silicon where as a factor of 10 4 is achieved when it is adsorbed on the silver particles deposited on porous silicon. The experimental results also showed that the enhancement electrodeposition when all other conditions are the same. |
