Figure 9.34 . (a) An HR-TEM image of the intact C 60 peapods. (b) HR-TEM images of
the iodine-doped C 60 peapods with low doping ratio; the black spots (indicated by
arrows) are ascribed to the doped iodine atoms. (c) The best it schematic model
(purple, iodine; gray, carbon). (d) An HR-TEM image of the iodine-doped C 60 peapods
with higher doping ratio; the bent chains (indicated by arrows) are ascribed to the
doped iodine species. (e) The schematic model. Scale bar = 2 nm. Reproduced from

Figure 9.35 . Raman spectra of the iodine-doped C 60 @SWCNTs before and after heat
treatment. The arrow indicates the newly appearing RMB mode as the result of heat
treatment. Inserted are typical HR-TEM images of the iodine-doped C 60 @SWCNTs
after heating. Reproduced from Guan et al . 202 with permission.
