| 摘 要： | 以绘画纸、白卡纸和坐标纸为衬底,采用丝网印刷银油墨,制备了高效的表面增强拉曼散射(SERS)基底,结果表明:银薄膜/绘画纸的SERS活性最佳,其次是银薄膜/白卡纸和银薄膜/坐标纸,对结晶紫的最低检测限分别为10-8,10-7和10~(-7)mol·L~(-1).此外,在同一银薄膜/绘画纸表面随机选取10个不同位置,在特征峰913,1 179和1 620 cm~(-1)处,强度的相对标准偏差值分别为13.2%,12.5%和10.6%,增强因子达到2.87×105,表明该基底具有较好的均匀性.

| Abstract: | An efficient surface enhanced Raman scattering(SERS)substrate was prepared by screen printing silver ink on drawing paper, white card paper and coordinate paper. The results showed that silver film/drawing paper represented the best SERS activity, followed by silver film/white card paper and silver film/coordinate paper. The minimum detection limits for crystal violet were 10-8, 10-7 and 10-7 mol·L-1, respectively. In addition, ten different positions were randomly selected on the same silver film/drawing paper surface, and the relative standard deviation values of the peak intensitiesat 913, 1 179 and 1 620 cm-1 were 13.2%, 12.5% and 10.6%, respectively, which indicated outstanding uniformity. |
