Development of Tailored Graphene Nanoparticles: Preparation, Sorting and Structure Assessment by Complementary Techniques.

In this respect, it is instructive to compare our result with those reported in [ 31 ], where an increasing trend of I2D/IG has been observed for samples made of graphene particles while passing from thicker to thinner GNPs: on this ground, the authors [ 31 ] provide an empirical relationship between <N> and I2D/IG, which can be exploited to obtain the value of <N> from the Raman measurements (at 532 nm).

(iv) Interestingly, the intensity of D1, D2, and D3 is scarcely affected by the kind of nanoparticles, and it shows a decreasing trend with the decreasing of the exciting laser wavelength.
