| 摘 要： | 在碳60（C60）[1]和碳纳米管(CNTs)[2]发现之前，人们知道碳通常显示石墨和金刚石两种晶体结构.自从C60和碳纳米管发现后，由于其独特的纳米结构而具有广泛的应用前景，国内外许多学者致力于研究它们的物理和化学特性，而C60、巴基葱（多层碳纳米球）、碳纳米管和金刚石之间的转变是所研究的焦点之一.目前，由碳的其他形式向金刚石转变的主要方法有：Meilunas等人[3]以C60和C70薄膜为基底气相生长多晶金刚石,C60和C70的稳定性和微平面结构在外界条件下，有利于金刚石成核和外延生长；Banhart[4]小组研究了在电子束辐射作用下巴基葱转变…

| Abstract: | The transition from carbon nanotubes to diamond nanocrystals by vacuum evaporation is reported. The nanocrystals were characterized by transition electron microscopy (TEM) and high resolution transition electron microscopy(HRTEM). The micrographs and corresponding diffraction patterns showed that the nanocrystals with perfect crystal structure conformed to diamond clusters. The transition mechanism and process are primarily discussed. |
