Enlarged 2D band regions of micro-Raman spectra measured on samples. Type I (a) and type II (b). Open circles are the experimental data, while the green and red curves indicate the fittings of the experimental data by Lorentzian functions. The fitting peaks and peak sum are shown by the green and red curves, respectively.
