Raman spectra from different synthesized samples using 532 nm (1.958 eV) laser as an excitation source. The D- and G-bands at 1354 cm1 and 1597 cm1, respectively, for graphite are indicated by the vertical line. The ratio of the intensity of the D- Raman peak to the G- Raman peak (ID/IG) is indicated for each sample. The non-null value of the ID/IG ratio indicates the presence of defects in the graphite layers.
