| 摘 要： | 用表面增强拉曼散射技术研究单晶硅表面键合光敏染料，可获得信噪比强的ＳＥＲＳ图。因染料分子中含有孤对电子的氮原子和起增强作用的银离子相互作用，使Ａｇ＋成为连结染料分子间的锁，增加染料分子极化率，使拉曼散射截面积增大，从而起到增强效果的作用。

| Abstract: | The photosensitive dye bound to the monocrystalline silicon surface was investigated by means of SERS, and SERS which had strong signal-to-noise ratio (SNR)was obtained. Our work suggests that the interaction of Ag acting as enhancement and N atom having alone electron pair in dye. made Ag a lock linking dyes. So, the polarizability of dye molecule and the sectional area of Raman Scattering were increased, and enhancement effect was obtained. |

| Keywords: | monocrystalline silicon surfacel bindings surface enhanced Raman scattering photosensitive dye |
