Concentration of C60 Molecules in SWCNT

Abstract

Recently, it was possible to fill single wall carbon nanotubes with C60 fullerenes resulting in carbon structures with new and interesting properties (so‐called C60 peapods). All Raman allowed modes of the free C60 were identified for the encaged C60. In this contribution we demosntrate how the concentration of the peas in the SWCNT pods can be obtained from a detailed analysis of the Raman spectra of the peapods.
