Abstract
Luminescence spectra of barium cerate BaCeO3, a starting material in the family of mixed conductors with protonic and oxygen conduction, are studied for the first time. The photoluminescence of this material is shown to be due to transitions involving cerium ions. A model of the recombination process is proposed. The luminescence of samples subjected to various post-growth treatments is measured, and the connection between the type of the treatment and the specific changes in the luminescence spectra is interpreted.
