Amorphization of C60 nanotubes under pressure

C60 nanotubes with diameters of smaller than 500 nm are fabricated by a modified liquid–liquid interfacial precipitation method. In situ angle dispersive synchrotron x ray diffraction and Raman scattering under pressures have been employed to study the structure evolution of the C60 nanotubes. The e...

Zusammenfassung:C60 nanotubes with diameters of smaller than 500 nm are fabricated by a modified liquid–liquid interfacial precipitation method. In situ angle dispersive synchrotron x ray diffraction and Raman scattering under pressures have been employed to study the structure evolution of the C60 nanotubes. The experimental results indicate that there is a pressure induced irreversible amorphization at 40.1 GPa. An isostructural phase transition occurs in the pressure range of 9.29–12.2 GPa, which is probably relative to the changes in the bonding type of C60 nanotubes.
