摘要：

We present the Raman characterization of transformed fullerene samples obtained by applying high (approximately 20 GPa) nonhydrostatic pressures on C60 or C60-C70 powders. Only two clear features are observed. The first is a peak at 1330 cm-1, signature of the existence of cubic diamond. The second is a broadband of unknown origin centered at approximately 1450 cm-1. These results confirm previous crystallographic analysis that showed that our samples consist of polycrystalline diamond embedded in an amorphous matrix.
