WebSurface-enhanced Raman scattering (SERS), a novel analytical technique, has the superiority of enhancing Raman signals up to 10 4 –10 7 magnitude compared to traditional Raman spectroscopy. 13 Furthermore, ... Spectra were accumulated 1 scan with an exposure time of 10 s. The beam diameter was approximately 1 mm on the sample surface. WebDelays at cathodic and anodic vertex potentials are 10 and 2 s, respectively. Cathodic and anodic scan rates are 500 and 1000 mVs-1, respectively. The ORC cycle is 25 times. Also, the result indicates that the SERS effect decreases with increasing the charge passed for PPy deposition.
