Ion irradiation of carbon nanotubes encapsulating cobalt crystals
Abstract
The response of multi-walled carbon nanotubes encapsulating Co nanorods to ion irradiation was studied. The irradiation experiments with medium ion energies (40-500 keV) were carried out at high temperatures and combined with transmission electron microscopy and Raman characterization of the irradiated samples. Contrary to electron irradiation and high-energy (100 MeV) ion irradiation, we did not see accumulation of pressure inside irradiated nanotubes. We found that nanotubes with Co nanorods inside were transformed to amorphous carbon rods encapsulating Co clusters with typical diameters of 3-6 nm. As Co is magnetic, such one-dimensional composite systems could be used for various applications such as magnetic data storage or magnetic resonance imaging. (C) 2007 Elsevier B.V.
