Abstract

Single-walled carbon nanotubes (SWCNTs) were filled with ferrocene molecules and the inner tube growth inside the filled SWCNTs that occurred during vacuum annealing at temperatures between 500 and 1000??C was studied by Raman spectroscopy. The quantitative analysis of Raman spectra revealed that the growth temperatures of inner tubes increase by ?110??C with increasing the tube diameter by ?0.3?nm and that they do not depend on the chiral angle. The growth temperatures of inner tubes inside ferrocene-filled SWCNTs are also compared with those reported for cobaltocene- and nickelocene-filled SWCNTs. We find that the growth temperatures of inner tubes decrease in the line with ferrocene-cobaltocene-nickelocene.
