In this study, electrochemically roughened gold is modified with underpotential deposition (UPD) silver to investigate the effects on enhancements in the intensity and the thermal stability of surface-enhanced Raman scattering (SERS). The SERS of Rhodamine 6G (R6G) adsorbed on the UPD Ag-modified Au substrate exhibits a higher intensity by six-fold of magnitude, as compared with that of R6G adsorbedon the unmodified Au substrate. Moreover, the SERS enhancement capabilities of UPD Ag-modified Au and unmodified Au substrates are seriously depressed at temperatures higher than 200 and 150 degrees C, respectively. It indicates that the modification of UPD Ag can significantly depress the thermal destruction of SERS-active substrates. Copyright (C) 2009 John Wiley & Sons, Ltd.
