▎ 摘　　要

NOVELTY - Multilayered hollow nanographene is formed by graphene layers, where external diameter of nanographene is 25-300 nanometers and inner diameter is 6-250 nanometers. The nanographene has an interplanar distance of 0.34-0.60 nanometers and thickness of 3.4-60 nanometers. USE - Multilayered hollow nanographene for use in light-emitting optical structure (claimed). ADVANTAGE - The multilayered hollow nanographene has semiconducting property and physicochemical properties similar to that of carbon nanotube or fullerene. DESCRIPTION OF DRAWING(S) - The drawing shows a high-resolution transmission electron microscope photograph of composite.
