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.
我们报道了一种新结构，即由ZnO纳米晶体通过纹理自组装形成的介孔结构多面体鼓以及球形笼和壳，它们是在外延表面氧化过程中通过一种新型自组装工艺制备而成的。这些笼/壳呈现出独特的几何形状，其壁由介孔和纹理化的ZnO纳米晶体组成。对笼和壳的结构进行了研究，并提出其生长机制是一个遵循Zn液滴凝固、表面氧化和升华的过程。
