摘要：
Thermal desorption spectroscopy has been carried out on thin fullerene films containing endohedral Li @ C-60 and produced by low-energy ion bombardment. The desorption properties of the films were studied as a function of the film thickness, ion energy, and ion dose. The results provide strong corroborative evidence for the endohedral nature of the Li-containing species and also clearly indicate the prescence of Li-2 @ C-60 in the films. The binding energy in these films is significantly larger than in pure C-60 films and evidence of degradation of the fullerenes is seen at high ion energies and/or large ion doses.
