Abstract
Surface-enhanced Raman scattering (SERS) from bare roughened Fe electrodes was observed by confocal Raman microscopy for the first time. The combinati on of SERS and STM measurements indicates that a proper surface-roughening procedure is indispensable for obtaining good-quality surface Raman spectra from bare bulk Fe electrodes. The surface-enhancement factors for various roughened Fe surfaces were calculated to range from two to three orders, cr itically depending on the roughening procedure. The lightning rod effect ma y mainly contribute the surface-enhancement on the Fe surfaces. (C) 2000 El sevier Science B.V. All rights reserved.
