Low temperature fullerene encapsulation in single wall carbon nanotubes: synthesis of N@C 60@SWCNT
High filling of single wall carbon nanotubes (SWCNT) with C 60 and C 70 fullerenes from solvent is reported at temperatures as low as 69 °C. A 2-h long refluxing in n-hexane of the mixture of the fullerene and SWCNT results in a high yield of C 60,C 70@SWCNT, fullerene peapod, material. The peapod f...

70 fullerenes from solvent is reported at temperatures as low as 69 °C. A 2-h long refluxing in
n-hexane of the mixture of the fullerene and SWCNT results in a high yield of C

70@SWCNT, fullerene peapod, material. The peapod filling is characterized by TEM, Raman and electron energy loss spectroscopy and X-ray scattering. We applied the method to synthesize the temperature sensitive (N@C
