摘　　要：研究了一种新的表面增强拉曼活性银基底的制备方法,采用银增强剂和引发剂的混合溶液处理全铝表面制备了银基底,利用扫描电子显微镜分析了基底的表面形态和结构,测定结晶紫分子在基底表面的拉曼光谱。结果表明,这种基底具有很强的表面增强拉曼散射效应(SERS)活性和稳定性。A new method for preparing SERS-active substrate was reported.The prefabricated aluminum foils was immersed into the mixture of silver enhancer and initiator for 30 seconds and then rinsed by doubly distilled deionized water.Surface morphology and structure was analyzed by SEM.The measurements of the SERS spectra of crystal violet on the substrates indicate that such a silver substrate has better SERS activity and stability.
