用YAG脉冲激光器烧蚀去离子水中的Ag片,得到高分散均匀的Ag纳米胶体,通测试发现此Ag胶体系是一种非常高效的SERS活性增强基底,并对其与对羟基苯甲酸的吸附行为做了简要分析
YAG pulsed laser was used to ablate the Ag plate in deionized water to obtain highly dispersed Ag nanocolloid. The Ag colloidal system was found to be a very efficient SERS activity-enhancing substrate and its adsorption to p-hydroxybenzoic acid Behavior made a brief analysis
