Abstract：
We have successfully synthesized C₇₀ rods in nano/sub-micrometers scale by evaporating solvent method. The diameter of the as grown C₇₀ rods is ～500 nm, and the length is ～10μm. The EDXD pattern and Raman spectroscopy for as -grown sample indicate that the as grown C₇₀ rod is in hcp structure. The pressure-induced structural phase transition has been studied by using DAC combined with EDXD and Raman spectroscopy methods under quasi-hydrostatic pressure up to 26.1GPa. It is found that hcp structure transforms into amorphous phase for C₇₀ rods in the pressure range from 23.3 to 26.1GPa, which is higher than the transformation pressure for bulk C₇₀ crystals. The phase transition is irreversible and it is induced by the collapse of C₇₀ cage.
