title: Note: Simultaneous measurement of surface plasmon resonance and surface-enhanced Raman scattering.
abstract: A surface plasmon resonance (SPR)-surface enhanced Raman scattering (SERS) microspectrometer was designed to obtain the incident angle dependence of SERS signals excited by the evanescent field. By simultaneous measurement of the SERS and SPR spectra of analytes, the highest SERS signal intensities were found to appear at the vicinity of the resonance angle. The enhancement factor was about 2.0x10(6). The simulated angle of the maximal SERS intensity based on Fresnel equation was found to be in good agreement with the experimental results. The SERS and SPR spectra captured simultaneously not only directly confirm the correlation between the SERS and SPR but also present a potential technique for obtaining the structure information about the analytes in molecule level with recording their SPR curves.
