| Abstract: | Good-quality surface enhanced Raman spectra have been obtained from various roughened Pt electrodes using a confocal Raman measuring system. A new equation is presented to estimate the enhancement factor G for the electrodispersed and platinized Pt electrodes in a pyridine+NaClO4 solution. It is shown that the platinum electrodes undergoing the special roughening procedures exhibit a weak SERS effect with an enhancement factor of 10 to 1.2×102, depending on the surface pretreament. |
