摘要：

用Y2O3、碳粉复合棒为原料，经过二步直流电弧反应，从所得的烟炱中在惰气保护下用CS2萃取出了Y＠C2n（2n=60，70，80，84，90，96）和Y2＠C96. 样品经场解吸质谱（FDMS）和电子顺磁共振（EPR）表征, 皆发现，Y＠C84和Y＠C90的含量最高且是稳定。

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.
