| 摘 要： | 本文利用表面增强拉曼光谱研究了增感染料1556、798在银电极上的吸附,通过比较染料的固体拉曼光谱和染料的表面增强光谱,我们发现两种染料在银电极表面的吸附行为不完全相同,吸附时染料分子的平面基本上与电极表面相垂直。

| Abstract: | Two model systems, Ag/NaBr+Dye-798 and Ag/NaBr+Dye-1556 have been used in this work. The orientation of the dye molecules, adsorbed on the surface of silver electrode, the stabilization of adsorption, and the competition between two adsorbed dyes were studied by the method of SERS (Surface Enhanced Raman Spectra).By the comparison of Raman Spectra of solid dyes and SERS of adsorbed dyes, it was found that those two dyes have different adsorption behaviors on the surface of silver electrode, and the molecules of two dyes are almost perpendicular to the electrode surface. |
