Abstract:

 With Y2O3/carbon composite rods, Y@C2n(2n=60, 70, 80, 84, 90 and 96)and Y2@C76 are synthesized by two-steps arc-vaporizing method and extracted from the soot with CS2 under the protection of inert gas. The samples are characterized by field desorption mass spectrometry (FDMS) and electron paramaganetic resonnance (EPR). It is also found that Y@C84 and Y@C90 are the most abundant and stable.

Key words: Endohedral metallofullerene, Yttrium, Two-steps arc discharge method
