The investigation of the structure and electronic properties of carbon onions was presented. It was shown that diamond nanoparticles are transformmed into spherical carbon onions on annealing at 1700°C by high-resolution transmission electron microscopy (HRTEM).On studying HRTEM, Raman spectroscopy and electron spin resonance, the presence of π electrons was depicted. It was suggested that the spherical onions consist of small domain of graphite sp2 sheets dangling bond defects in the peripheries.
