银溶胶体系是用于研究增强拉曼 ( SERS)的重要体系 ,最近人们用银溶胶体系进行了许多物质的 SERS研究 [1 - 5] .本研究用柠檬酸钠和硼氢化钠还原硝酸银均得到了银溶胶 ,用电泳、透射电镜 ( TEM)和紫外 -可见光谱方法研究了银溶胶的性质 .在用柠檬酸钠还原法制备的银溶胶体系中
Silver sol system is an important system for the study of Raman enhancement (SERS). Recently, many SERS studies have been performed on silver sol systems [1-5] .In this study, silver nitrate was reduced with sodium citrate and sodium borohydride The silver sol was obtained and the properties of the silver sol were investigated by means of electrophoresis, transmission electron microscopy (TEM) and UV-Vis spectroscopy. In the silver sol system prepared by sodium citrate reduction
