2017 m. Nr. 1 Raman spectroelectrochemical study of electrodeposited Prussian blue layer: dependence of spectral intensity on underlying electrode roughness
Prussian blue (PB) has been electrodeposited at a smooth and at an electrochemically roughened gold electrodes as a thin layer of a few tens of nmol/cm2 coverage (or a few tens of nanometers thick), and studied by Raman spectroelectrochemical technique using 785-nm laser excitation. It has been shown that the spectra obtained from a roughened electrode are by one order of magnitude more intense than those obtained from a smooth electrode. This shows that even at a relative thick layer of a modifier PB the surface enhancement of Raman spectra plays an important role in obtaining well-defined spectra from modified electrodes.
