摘　　要：利用高能离子注入技术系统地研究了不同剂量、不同种类离子注入对Ｃ６０薄膜结构的影响，并利用Ｒａｍａｎ光谱对其结构进行分析．结果表明：中等能量的离子注入会影响Ｃ６０薄膜的结构，使Ｃ６０分子薄膜产生聚合和非晶碳化现象，但上述现象的出现与注入离子的剂量大小有关，并存在一注量阈值，只有在此阈值之上，Ｃ６０薄膜结构才发生改变。Abstract C 60 films were irradiatied at room temperature by medium energy(120 360keV) radiation of different ions (H +,He +,N +,Ar +), and the radiation effects were investigated using Raman spectra. The results showed that the radiation of medium energy ions could cause C 60 films polymerized and amorphous. However, occurrence of the phenomena depends on dosage, which is related to the interaction between the radiation ion and C 60 molecule. A possible explanation for the experimental results is given and the mechanism of the interaction between the radiation ion and C 60 molecule is discussed.
