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.
