我们报告了一种新的结构，介孔结构的多面体鼓形和球形笼和壳形成的纹理自组装的ZnO纳米晶体，这是由一种新的自组装过程中的外延表面氧化。笼/壳具有独特的几何形状，其壁由介孔和织构化的ZnO纳米晶体组成。笼和壳的结构进行了研究，并提出了一个生长机制是一个过程，以下的Zn液滴的凝固，表面氧化，升华。
We report a new structure, mesoporous structured polyhedral drum and spherical cages and shells formed by textured self-assembly of ZnO nanocrystals, which are made by a novel self-assembly process during epitaxial surface oxidation. The cages/shells exhibit unique geometrical shapes, and their walls are composed of mesoporous and textured ZnO nanocrystals. The structures of the cages and shells are studied, and a growth mechanism is proposed to be a process following solidification of the Zn liquid droplets, surface oxidation, and sublimation.
