| 摘 要： | 将激光消融质谱技术应用于碳笼内部嵌入钇原子形成含钇碳笼包合物的研究．实验采用石墨/Y2O3组合棒电弧蒸发法制备含钇碳笼包合物．激光消融质谱实验结果表明，YC82存在且聚集在样品表面，不同条件下制备的YC82的产额不同．此外，还研究了YC82在空气中稳定性的问题，并从理论上分析了YC82存在的原因关键词：

| Abstract: | Laser ablation mass spectroscopy (LAMS) has been used to study yttrium contained fullerenes. Yttrium contained fuller enes were prepared by arc burning of Y2O3/graphite composite rods. The LAMS exper imental results confirm the presence of YC82．It was also shown that YC82 appears on the surface of the sample and that the yield of YC82 changes with the primitive weight ratio of Y2O3 to graphite in fabrication processing. In addition, the stability of YC82 in air was studied and the mechanism of YC82 formation was discussed. |
