C 60 Filling Rate in Carbon Peapods: A Nonresonant Raman Spectra Analysis

We calculated the nonresonant Raman spectra of C 60 peapods to determine the concentration of C 60 fullerenes inside single-walled carbon nanotubes. We focus on peapods with large diameters for which C 60 molecules can adopt a double helix configuration or a two-molecule layer configuration. Our cal...

Summary:We calculated the nonresonant Raman spectra of C 60 peapods to determine the concentration of C 60 fullerenes inside single-walled carbon nanotubes. We focus on peapods with large diameters for which C 60 molecules can adopt a double helix configuration or a two-molecule layer configuration. Our calculations are performed within the framework of the bond-polarizability model combined with the spectral moment’s method. The changes in the Raman spectra as a function of C 60 filling rate and the configuration of C 60 molecules inside the nanotubes are identified and discussed. Our calculations support the experimental method proposed by Kuzmany to evaluate the concentration of C 60 molecules inside nanotubes.
