Abstrakt

We report on the preparation and subsequent Raman analysis of carbon nanotube peapods, using the fullerene C60 and its heterofullerene derivative (C59N)2 as filling materials. The filling with (C59N)2

was done from liquid solution at room temperature and from the gas

phase at elevated temperatures. The success of the encapsulation

procedure is confirmed through the identification of fingerprint Raman

modes and the conversion to double wall nanotubes through heating to

1250 °C. The 2D mode of double wall nanotubes made from (C59N)2 peapods is observed to be downshifted compared to the same mode in double wall nanotubes made from C60 peapods. We interpret this downshift as an evidence for the integration of the nitrogen into the lattice of the inner tube.
