将微孔滤膜浸入柠檬酸三钠和硝酸银混合液通过微波加热银化制得一种新型、高活性的SERS活性基底。以结晶紫为探针分子,采用便携式拉曼光谱仪检测其SERS活性,同时探讨浸泡时间与SERS活性的变化关系。实验结果显示,在浸泡2～8小时区间,基底的SERS活性随着浸泡时间的增加而增强。 The porous membrane was immersed in a mixture of trisodium citrate and silver nitrate to obtain a novel and highly active SERS-active substrate by microwave heating and silvering. The crystal violet was used as the probe molecule, and the SERS activity was detected by portable Raman spectrometer. The relationship between the soaking time and the SERS activity was also discussed. The experimental results showed that the SERS activity of the substrate increased with the soaking time from 2 h to 8 h.
