Abstract

CeO₂ nanocubes, truncated nanocubes, and truncated octahedra were synthesized for the preparation of long-range ordered self-assembly multilayered nanostructure. The multilayer of CeO₂ nanocrystals was prepared on a rapid enlarged liquid-gas interface with a high concentration of surfactant in the dispersion. The structure of multilayers was decided by the crystal face of CeO₂ nanocrystals and the exposed crystal face of the multilayer, via which the orientation of nanocrystals in the self-assembly structure could be controlled. A novel formation mechanism for the self-assembly structure was demonstrated.
