| 摘 要： | 用60keV的Ni+和Ar+在相同实验条件下,先后分别辐照同一块石墨靶,剂量均为1018/cm2.带能量色散X射线分析和电子衍射分析的高分辨透射电子显微镜观察和分析发现,尺寸不同的纳米Ar泡嵌在类玻璃碳薄片中,部分泡内的Ar可能已形成固体结构.

| Abstract: | The identical graphite targets were irradiated by 60keV Ni+ and Ar+ ions with the fluences of 10 18/cm2 in turns under the same experimental conditions. Using high-resolution transmission electron microscope (HRTEM) with energy dispersive X-ray (EDX) and electron diffraction (ED), we found different-size nanoscale Ar-bubbles embedded in glass-carbon-like membranes for the first time. Moreover, in part of these nanobubbles Ar may have been formed into a solid-like structures. |
