在线性胺存在下，通过羰基钴的快速分解得到hcp Co盘状纳米晶体。除了胺之外，其它表面活性剂如氧化膦和油酸用于改善尺寸分散、形状控制和分散稳定性。钴盘是铁磁性的，它们自发地自组装成长带。X射线和电子衍射，电子显微镜，SQUID磁强计已被用来表征这种材料。
hcp Co disk-shaped nanocrystals were obtained by rapid decomposition of cobalt carbonyl in the presence of linear amines. Other surfactants, in addition to the amines, like phosphine oxides and oleic acid were used to improve size dispersion, shape control, and nanocrystal stability. Co disks are ferromagnetic in character and they spontaneously self-assemble into long ribbons. X-ray and electron diffraction, electron microscopy, and SQUID magnetometry have been employed to characterize this material.
