The doped polyaniline (PANI) films with different thickness electrodeposited on flat platinum electrode surface have been studied by confocal Raman spectroscopy. It was found that the overall features of the Raman spectra depend strongly on the confocal depth. Therefore, it can be deduced that the doping level of the PANI film increases with film thickness during film growing process. X-ray photoelectron spectroscopic (XPS) analysis and ultraviolet-visible (UV) absorption spectrum results also confirmed this idea.
