摘要
In this paper, the formation of the CuxC60 films has been described briefly. The UV- Vis absorption spectrum of CuxC60 film have been discussed in detail, the electronic structure of CuxC60 film is discussed qualitatively. For x< 1, there exists only Cu＋ in the CuxC60 films. However, for x=4, not only Cu＋ , but also atom- Cu exists in them. In CuxC60 films three strong peaks have been shiffed compared with that of C60 films. The shift of these strong peaks shows that in the CuxC60 films C60 molecule accepts only one electron and becomes . Because of the existence of the atom- Cu in the CuxC60 films, in visible region there is a wide peak which is the plasmons resonance absorb peak of the Cu- cluster in it.

Because of the existence of the atom-Cu in the CuxC60 films, in visible region there is a wide peak which is the plasmons resonance absorb peak of the Cu-cluster in it.
