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.
