| 3 | Plasmonic response of gold film to potential perturbation显示文摘Gold film (~50 nm) serves as the working electrode to allow the electrochemical process to be monitored using surface plasmon resonance (SPR) technology. The extracted precise value of time resolved SPR signal perturbed by the non-faradic potential was investigated to study the response time of gold film under potential application. A qualitative model of the reflection and transmission spectra of gold film working as the electrochemical interface is presented. The correlation between three parameters, including thickness of gold film, incident angle and wavelength of beam, were analyzed to generate an optimized configuration for gold film to detect potential. These results emphasis the efficiency of SPR technique used as a diagnostic tool for the electrochemical process. | HUANG Yu PITTER Mark C SOMEKH Michael G ZHANG Wei XIE WanYi ZHANG Hua WANG HuanBo FANG ShaoXi | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，8： | 0 |
