| 摘 要： | 采用循环伏安法(CV), 在ITO玻璃表面一步法电沉积了花状的Au@R6G(罗丹明6G)复合纳米粒子膜, 该膜呈现很强的表面增强拉曼散射(SERS)活性, 比传统制备金膜的方法提高了一个数量级。采用扫描电子显微镜(FE-SEM), X射线衍射光谱(XRD), 拉曼光谱对复合纳米粒子进行表征。通过实验发现, 电沉积20圈时的Au@R6G样品SERS信号增强最为显著, R6G的SERS检测限可达到10-10 M。

| Abstract: | One step to form the flowerlike Au@R6G(Rhodamine 6G) nanocomposite particles at the surface of ITO glass was developed by cyclic voltammetry and resulting Au@R6G exhibited a strong surface-enhanced Raman scattering(SERS) effect,which one-folder higher than Au@R6G SERS-active substrates normally prepared in presenting literatures.In this work,the products were characterized by FE-SEM,XRD and Raman spectroscopy.The experimental results showed that the SERS signal of Au@R6G made under the 20 electrodeposition cycles reached the maximum.Moreover,LOD of this improved SERS substrate based on this strategy can reach 10-10M for the R6G. |
