项目摘要

The endohedral metallofullerene K@CィイD260ィエD2 was successfully formed by the energy and flux control of KィイD1+ィエD1 and CィイD1-ィエD1ィイD260ィエD2 ions flowing into substrates in experiments of the thin-film formation with a potassium-fullerene (KィイD1+ィエD1-CィイD1-ィエD1ィイD260ィエD2) plasma. Since the K@CィイD260ィエD2 production ratio to CィイD260ィエD2 was at most 30% and usually 5〜10% or less, however, it was difficult to clarify the relation between the plasma effect and encapsulation mechanism. From the above-mentioned viewpoint, the experiments were carried out by a sodium-fullerene (NaィイD1+ィエD1-CィイD1-ィエD1ィイD260ィエD2) plasma, where the diameter of NaィイD1+ィエD1 is smaller than that of KィイD1+ィエD1. The following results were obtained.According to the mass analysis of thin films formed on the substrates, the large mass-spectrum peak (Na(@)CィイD260ィエD2) corresponding to the Na-endohedral fullerene is observed. The average intensity ratio of Na(@)CィイD260ィエD2 to CィイD260ィエD2 is turned out to be 30〜50%. Moreover … More , the Na(@)CィイD260ィエD2 production ratio to CィイD260ィエD2 in a narrow region of the substrate attains to 200% or more.When the substrate bias is changed, the average spectrum-peak intensity of Na(@)CィイD260ィエD2 is found to give the maximum value at a specific voltage.The composition and structure of the thin film are directly investigated by the high-resolution electron microscope (HREM) observation. A lot of CィイD260ィエD2 molecules with dark shadows around the centers are observed over the image of the thin film in the narrow region of the substrate. The round material imaged by the HREM is considered to be CィイD260ィエD2 encapsulating Na inside the cage, because the NaィイD1+ィエD1 diameter almost corresponds to the dark shadow diameter.It can be said that a large amount of production of the Na-CィイD260ィエD2 compound materials containing Na@CィイD260ィエD2 facilitates the constituent analysis and structure observation for the purpose of clarifying their physical and chemical properties. This work is also important in the sense of establishing the method of forming fullerene-based thin films with new functions. Less

在钾富勒烯薄膜形成实验中，通过控制流入基板的KィイD1+ィエD1和CィイD1-ィエD1ィイD260ィエD2离子的能量和通量，成功形成了内嵌金属富勒烯K@CィイD260ィエD2 （KィイD1+ィエD1-CィイD1-ィエD1ィイD260ィエD2）等离子。然而，由于K@CィイD260ィエD2相对于CィイD260ィエD2的生成比例至多为30%，通常为5〜10%以下，因此难以明确等离子体效应与封装机制之间的关系。从上述观点来看，实验是在钠富勒烯（NaィイD1+ィエD1-CィイD1-ィエD1ィイD260ィエD2）等离子体中进行的，其中NaィイD1+ィエD1的直径小于KィイD1+ィエD1的直径。获得以下结果。根据在基板上形成的薄膜的质量分析，观察到对应于Na-内嵌富勒烯的大质谱峰(Na(@)CィイD260ィエD2)。 Na(@)CィイD260ィエD2与CィイD260ィエD2的平均强度比为30〜50%。此外，在基板的狭窄区域内，Na(@)CィイD260ィエD2与CィイD260ィエD2的产率达到200%以上。当改变基板偏压时，发现Na(@)CィイD260ィエD2的平均谱峰强度在特定电压下给出最大值。薄膜直接由高分辨率电子显微镜（HREM）观察。在基板狭窄区域的薄膜图像上观察到许多中心周围有暗影的CィイD260ィエD2分子。 HREM成像的圆形材料被认为是CiiD260ィエD2将Na封装在笼内，因为NaィイD1+ィエD1直径几乎对应于暗影直径。可以说，大量生产的Na-CiiD260ィエD2复合材料含有Na@CィイD260ィエD2有利于成分分析和结构观察目的是明确其物理和化学性质。这项工作对于建立具有新功能的富勒烯基薄膜的形成方法也很重要。较少的
