我们在这里通过原位高分辨率透射电子显微镜报告了碳洋葱的逐壳形成。最里面的富勒烯种子首先形成并充当中心成核核以产生多壳碳多边形。然后，通过所谓的“热收缩”过程，碳多边形可以以可控的方式进一步转化为碳洋葱。
We report here a shell-by-shell formation of carbon onion by means of in situ high-resolution transmission electron microscopy. An innermost fullerene seed first forms and acts as the central nucleation core to produce a multishell carbon polygon. Then, the carbon polygon can be further transformed to the carbon onions in a controllable manner through the so-called “hot shrinkage” process.
