Abstract

We have measured site-selective luminescence spectra of Eu³⁺ in the perovskite proton conductors Y³⁺-doped SrCeO₃ single crystals. A strong red shift of the ⁵D₀-⁷F₀ transition of Eu³⁺ is observed with H₂O-treatment. The site-selective spectra of these reveals that (i) four different sites of Eu³⁺ ions exist in protonated SrCeO₃ system at low Y³⁺ concentration and (ii) that the relative intensity among these sites strongly depends on the dopant concentration.
