异烟酸在银溶胶上的表面增强喇曼散射及影响因素

Surface Enhanced Raman Scattering (SERS) of Isonicotinic Acid Adsorbed on Silver Sol and Fators Affecting It

本文研究了异烟酸吸附在银溶胶表面的表面增强喇曼散射(SERS)光谱以及卤素离子、溶液pH值及溶液浓度对异烟酸SERS光谱的影响。文章提出了离子在银溶胶表面的吸附方式,即主要以—COO^-端吸附于银溶胶表面。最后,对所述实验现象作了定性讨论。

The surface enhanced Raman scattering spetra of isonicotinic acid adsorbed on silver soland factors affecting them, such as halide ions, pH, concentration of isonicotinic acid, werestudied. The isonicotinic ions are adsorbed by attaching their--COO^- moieties to the surfaceof silver sol.
