Abstract

Monodispersed CeO₂ nanocubes were prepared by using a liquid-liquid interface. The morphology of CeO₂ nanocrystals from the aqueous phase changed from truncated octahedron to nanocube in the toluene phase at the water-toluene interface. The CeO₂ nanocubes oriented to form large cubic particles at a low molar ratio of oleic acid (OLA)/Ce. The red-shift of the absorption edge and the high concentration of Ce³⁺ in the CeO₂ structure was identified for the CeO₂ nanocrystals. The high concentration of Ce³⁺ in the CeO₂ structure was identified as one of the main reasons for the red-shift of the absorption edge of CeO₂ nanocrystals.
