从纳米晶到三维超晶格结构 总被引：1，自引：0，他引：1
纳米晶的有序组装对未来纳米材料的应用拓展具有重要意义. 本综述介绍了纳米晶三维超晶格的研究价值以及制备方法,着重对“胶体溶液蒸发”、“不良溶剂扩散”、“胶束引导集聚”、“氢键连接”、“静电聚集”、“DNA导向”、“外场辅助”和“水－油界面辅助”的组装机制进行了总结与评述,同时也探讨了这一新兴领域中仍然存在的挑战. 相似文献

A series of cubic phase Co3O4 nano-leaves were prepared via a combined approach of solution reaction and calcination. According to x-ray diffraction and electron microscopy, we find that the Co3 04 grain size increases with calcination temperature. This can induce many gaps in the products. M-T and M-H magnetization measurements reveal the typical antiferromagnetie behavior of nano-leaves. The effective moments of the samples prepared at 300, 400 and 500℃ are 5.6, 5.8 and 5.7μB per formula unit （FU）, respectively, larger than the bulk value of 4.14 μB/FU. 相似文献
