Abstract

Blueshifts in the ultraviolet absorption spectra of cerium oxide nanocrystallites were observed. The blueshifts of cerium oxides were experimentally reconfirmed for diameters down to less than a few nanometers by a change in the electronic band structure. Relationships among the valence states of cerium ions, blueshift, and the particle size were formulated.
