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.
