Collapsed Deposition of Accelated C 60 Beam on Solid Surfaces ——Confocal Raman Microscopic Studies

Abstract Raman spectroscopy was applied to characterize the species deposited from the mass selected C 60 ion beam which was accelerated to 900 eV. The substrates for the deposition were (0001) surface of highly oriented pyrolitic graphite and (111) surface of gold crystal. The species do not exhibit the Raman scattering features of buckminsterfullerene, but displays the peaks at 1585 and 1332 cm -1 instead. The former peak is the character Raman peak of hexagonal graphite, and the latter can be attributed to the amorphous carbon in sp3 hybridization. The result reveals that C 60 was collapsed to be a new phase when it collides on the solid surface. The study also finds that the collision energy collapsing the cage structure of C 60 is around 400 eV, and the collapsed species does not fragment if the energy does not exceed 1 kV.
