Abstract

Optical reflectance spectra of CeO2 crystal have been measured in the photon energy range from 2.5 to 40 eV. A Kramers-Kronig analysis of the reflectance data has been performed to obtain the dielectric function and related functions. The observed spectral features can be explained in terms of the charge transfer and interband transitions and the atomic-like excitation of the Ce 5p core electron. A peak regarded as a candidate for the “4f2” feature has been observed at an excitation energy of 13 eV.
