摘要：

The ultraviolet (257 nm) Raman spectrum Of C-60 compressed to 30 GPa in a Mao-Bell diamond anvil cell with no pressure transmitting medium at ambient temperature indicates the formation of diamond after release of pressure. Previously, more extreme non-hydrostatic compression was reported to be required to form diamond from C-60. These results provide confirmation of the transformation of C-60 to diamond upon non-hydrostatic compression at room temperature and illustrate the utility of UV Raman spectroscopy for the analysis of carbon phases containing both sp(2) and sp(3) bonding.
