Multiwalled carbon nanotubes functionalized with europium-doped Y2O3 nanophosphors gives rise to species that are luminescent in the visible-light range. The surface morphologies and microstructure have been characterized by high-resolution transmission electron microscopy and Z-contrast imaging (see Figure). Such species may find potential applications in cancer diagnosis and treatment.
