Abstract:We report the synthesis of a novel isotope engineered C-13-C-12 heteronuclear nanostructure: single-wall carbon nanotubes made of C-13 enriched clusters which are embedded in natural carbon regions. The material is synthesized with a high temperature annealing from C-13 enriched benzene and natural C-60, which are coencapsulated inside host SWCNTs in an alternating fashion. The Raman 2D line indicates that the C-13 isotopes are not distributed uniformly in the inner tubes. A semiempirical method based modeling of the Raman modes under C-13 isotope enrichment shows that experimental data is compatible with the presence of C-13 rich clusters which are embedded in a natural carbon containing matrix.
