| 摘 要： | 在２００ｋｅＶ重离子加速器上，使用１２０ｋｅＶ的Ｈ＋，Ｈｅ＋，Ｎ＋，Ａｒ＋等离子对Ｃ６０分子薄膜进行了辐射处理，对辐射后Ｃ６０膜的Ｒａｍａｎ谱进行了系统地分析研究．离子辐射会影响Ｃ６０薄膜的结构，不同的辐射注入剂量会使Ｃ６０分子薄膜产生聚合和非晶碳化现象，这一现象的产生与辐射离子的剂量大小有关，并存在一剂量阈值．研究表明Ｃ６０分子的聚合与辐射碰撞过程中的电子能损有关，而Ｃ６０薄膜非晶碳化现象则主要受核能损的影响

| Abstract: | In this paper, the C 60 films have
been implanted at room temperature with 120keV H , He ,N and Ar ions by using a
200keV heavy ion accelerator. After that, the sample are investigated with Raman spectra. The
results show that the irradiation by medium energy ion could make C 60 films
polymerization and amorphism, also there is certain threshold dose for this phenomena, which
relate to interaction between the irradiation ion and C 60 molecule. Preliminary explanation
for experimental results is given and the mechanism of the interaction between irradiation ion
and C 60 molecule is discussed. |
