A. Kudelski et al., Surface-enhanced Raman scattering (SERS) on copper electrodeposited under nonequilibrium conditions, J MOL STRUC, 483, 1999, pp. 245-248
Rough Cu surfaces, with pattern formation, were obtained by a nonequilibriu
m electrodeposition from acidic electrolyte. Wavelength dispersive spectrom
eter (WDS)/energy-dispersive spectrometer (EDS) investigations revealed tha
t such surfaces are highly oxidized. Surface enhanced Raman scattering (SER
S) investigations confirmed a complex structure and composition of such a s
ubstrate; a distinct difference in spectral characteristics of an adsorbate
on Cu2O, pure metallic Cu clusters, and some other, not yet well character
ized, metallic Cu clusters, which predominate on the copper surfaces activa
ted by standard electrochemical methods, were identified and distinguished.
