Abstract
The structural features and morphology of the particles (globules) of technical carbon (TC) samples, both initial and those treated with pulsed laser radiation, were studied by means of high-resolution transmission electron microscopy. Measurements were carried out; the average distances between graphene layers (<i>d</i><sub>002</sub>), length and curvature of graphene layers in TC globules were calculated. Results of the investigation of structural transformations in TC samples irradiated with nanosecond laser pulses are presented. Changes of the average diameter of globules in TC samples determine the essential difference in the morphology of irradiated nanoparticles and in the lattice parameter <i>d</i><sub>002</sub>.
