采用高温退火法制备了规则分布的CoO纳米八面体阵列。通过调节热处理温度，可以控制纳米八面体的尺寸和间距。这些CoO纳米晶体的自组装线性阵列是由于固有的Rayleigh不稳定性引起的形态转变和由于钴的氧化引起的相变的协同作用的结果。(C)2010年美国物理研究所。[DOI：10.1063/1.3518470]
Arrays of regularly distributed CoO nano-octahedra are obtained by annealing Co nanowires at high temperatures. Both the size and the separation distance of the nano-octahedra can be controlled by tuning the annealing temperature. These self-assembled linear arrays of CoO nanocrystals result from the synergetic combination of the morphological transformation due to the intrinsic Rayleigh instability and the phase transformation due to the cobalt oxidation.
