常温常压下利用液-液界面生长法制备了不同形貌的C_(60)晶体,并对其生长机理进行了初步探讨.采用扫描电镜和X射线衍射分别对晶体形貌和结构进行了表征,结果表明,在CS_(2~-)异丙醇两相界面上可以生长形貌均匀的棒状晶体,且获得的晶体结构为简单六方.
Under normal temperature and pressure,the C_(60) crystal with different morphologies is prepared by liquid-liquid interface growth method,and the growth mechanism is studied simply.Their morphology and structures are characterized by scanning electron microscopy and X-ray diffraction.The results show that uniform rod-like crystal can be the grown in CS_(2~-)isopropanol two-phase interface,and crystal structure is simple cubic.
