http://ramanlife.com/applications/raman-spectroscopy-carbon-materials/ WebbTwo laser lines of 514 and 633 nm with a power of 0.5 mW on the sample were employed to excite the Raman spectra. Comparing the sample spectra to that of bulk alpha-Fe2O3, the sample Raman peaks were assigned. And it was found for the top-layer that the Raman frequencies were down shifted and the peak widths broadened.
