摘　　要：利用溶剂挥发法,通过甲苯和间二甲苯溶剂对富勒烯纳米晶结构和形貌的控制作用,合成垂直阵列结构的微尺寸的C_(60)纳米晶。利用SEM、Raman、XRD等方式对材料的形貌和结构进行了表征,并对其进行了电子场发射性能的研究。实验结果表明,实验中获得的样品是具有六棱柱形貌的C_(60)微米管/棒状材料;原始合成的C_(60)微米管/棒材料是具有六角(hcp)和面心立方(fcc)混合晶体结构的溶剂化微米晶体,在真空下加热处理可以去除掺杂在晶格内部的溶解,获得纯C_(60)微米晶阵列。实验发现,该C_(60)微米晶体阵列材料具有良好的场发射性能。C60 microtube\\rod arrays were fabricated by a modified solution evaporation method,evaporating a solution of C 60 in the mixture of toluene and m-xylene at room temperature.The morphology,size,phase structure and Raman spectrum of samples were characterized by scanning electron microscopy,X-ray diffraction and Raman spectrograph.The results indicated that arrays constitute of C 60 microtube/rod with hexangular morphologies were obtained.The XRD result showed a solvated structure mixed with hexangular and face centered cubic for the as-grown sample.C 60 microtube/rod arrays showed good field emission performance.
