Exploring the Concave Nanospace of Fullerenic Material

摘要

Summarizing we have demonstrated that the interior of the new fullerenic carbon cages provides an interesting nanoscale reactor for new materials and compounds which do not exist in the outside world. This is demonstrated explicitly from an analysis of dimetallo fullerenes where the Raman spectra give evidence for a strong bonding between the two rare earth ions inside the cage and the carbon atoms of the cage. The crystal field inside the cages reduces the local symmetry at the position of the rare earth atoms and a quadrupole interaction between the charged entities yields a doubling of the number of metal-cage modes.
