| 摘 要： | 制备出一种新的纳米银溶胶,与传统银溶胶相比,不仅可见光透过率高,而且还有较强的表面增强喇曼散射(SERS)效应.当阴、阳离子型分子分别吸附于其表面上时,喇曼与传统银胶相比表观增强分别约为400倍、70倍. |
| 关 键 词： | 纳米银 吸附分子 表面增强喇曼散射 |

| Abstract: | A new nano silver particle in silver colloid was prepared.Compared with the traditional nano silver the new nano silver in silver colloid has higher transparence and stronger SERS.It has been found that the Raman enhancement is about 400 times and 70 times when indolebutyric acid and pararosaniline reagent was adsorbed on the new nano silver |
| Keywords: | Nano silver Particle adsorption SERS |
