摘要：

We have measured site-selective luminescence spectra of EU(3+) in the perovskite proton conductors Y3+-doped SrCeO3 single crystals. A strong red shift of the D-5(0)-F-7(0) transition of EU(3+) is observed with H2O-treatment. The site-selective spectra of these reveals that (i) four different sites of EU(3+) ions exist in protonated SrCeO3 system at row Y3+ concentration and (ii) that the relative intensity among these sites strongly depends on the dopant concentration.
