| 摘 要： | SERS技术由于具有高灵敏度的表面效应,能够检测吸附在金属表面的单分子层或亚单分子层的分子,并能给出丰富的分子结构信息,因而己被广泛应用于界面科学以及定性和定量分析科学领域之中。本文在制备电化学沉积金纳米薄膜的基础上,利用扫描电镜观察金纳米薄膜的形貌,通过分析对巯基苯甲酸在电化学沉积金膜表面的SERS光谱,研究对巯基苯甲酸在金纳米薄膜表面的吸附方式。由SERS光谱分析,我们推断出对巯基苯甲酸可能通过羧基和S原子共同作用吸附在金纳米颗粒表面,且苯环平面可能与金薄膜表面成一定倾斜角。 |

| Abstract: | Since the first observation of surface-enhanced Raman scattering(SERS),this technology,with its very high surface sensitivity and selectivity,has emerged as a routine and powerful tool for the investigation and structural characterization of interfaces and thin-film solid materials.This paper reports that a new SERS-active gold film on the surfaces of a series of electric material has been prepared by an electrochemical technique in an aqueous solution of KAuCl4.With scanning electron microscopy,the morphol... |
| Keywords: | surface-enhanced Raman scattering(SERS) electrochemical deposition adsorption behavior |
