Could anywone help me to interpret the XRD and Raman spectra of the AC5 sample with respect to the others? Both spectra are clear to me for the samples AC1-AC4. However, the sample AC5 seems to be the most disordered (amorphous) judging from the Raman spectroscopy (the id/ig ratio is the avarage taken from several points). Meanwhile, the XRD spectra doesn't seem to confirm that - the C002 signal is shifted toward higher 2(theta) values (when compared to less disordered AC2-AC4 materials) and the other signal corresponding to C100 is very high. All the spectra have been nornalized against the maximum of the peak signal. I'm confused. I might only add that due to the low degree of crystalinity, each XRD spectra was extremely noisy after background substraction. I smootched it using Fourier Transformation, trying to apply a similar procedure for each sample.
Magdalena Skunik-Nuckowska when you measured the XRD patterns what was the speed? 2 theta/min? I would recommend to use 1 theta/min, and also put in the sample holder a little bit more of the sample (of course if you can). Regarding the XRD diffractograms' normalization, I would recommend against it, since if you do not normalize it and smooth it, the XRD pattern may look different. Regarding the Raman spectra the intensity ratio of D/G bands (ID/IG) provides information about the sp3/sp2 carbon ratio and is used as a measurement of disorder in carbon structures.
