Abstract:
A method for highly precise and high-resolution imaging and location of oxygen-containing groups on the walls of carbon nanotubes (CNTs) is presented. The soft-chemistry approach is used by means of tagging oxygen-containing groups on the surface of CNTs with Eu(III) through coordinate covalent bonds. Eu(III) ions bonded to oxygen-containing groups are observed by high-angle annular dark-field scanning TEM.
