The growth process of inner‐shell tubes from C 60 peapods and ferrocene (FeCp 2 ) filled single‐wall carbon nanotubes was studied with Raman spectroscopy and X‐ray diffraction (XRD). In the peapod case, it is shown that the Raman signal of the fullerenes decays about a factor five faster than the XRD peak of the 1D fullerene chain. The growth of the inner‐shell tubes coincides well with the 1D chain decay. In the FeCp 2 case, the inner tubes grow already at 600 °C in about one hour. Additionally, even for the same starting material, the inner‐outer tube pair distribution is different than for C 60 based inner tubes. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
