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。
In this paper, surface-enhanced Raman spectroscopy was used to study the adsorption of sensitizing dye 1556,798 on silver electrode. By comparing the solid Raman spectra of dye with the surface enhanced spectra of dye, we found that the adsorption behavior of the two dyes on the silver electrode surface is not Identical, the plane of the dye molecules adsorbed is substantially perpendicular to the electrode surface.
