Abstract

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