| 摘 要： | 报道使用Ｃ60粉末，利用双炉装置，通过闭管汽相法生长Ｃ60单晶的实验及结果。Ｃ60单晶的质量很好，较大单晶的尺寸为０．５ｍｍ×０．６１ｍｍ×１．０ｍｍ。Ｘ射线衍射和电子衍射图的分析得到室温下Ｃ60单晶为ｆｃｃ结构，确定了晶格常数，还进行了Ｒａｍａｎ光谱实验，实验结果表明，热、冷区温度及两者的温度差是影响大尺寸Ｃ60单晶汽相生长的主要因素，对此进行了详细的讨论。

| Abstract: | Millimeter-sized C60 single crystals were grown by the vacuum sublimation of the purified C60 powder in a sealed vacuum quartz tube. C60 single crystals, up to size of 0.5mm×0.6mm×l.0mm and free from solvent or C70, had excellent faces. X-ray diffraction, electron diffraction and Raman spectra measurement were carried out to determine the room-temperature structure of C60 single crystals. The experimental results show that the temperature T1 of the hot end of tube, the temperature T2 of the cold end of tube and the temperature gradient ΔT= T2- T1 are the primary factors for preparation of large C60 single crystals. The above growth conditions were discussed in detail. |
