Abstract

Infrared (IR) absorption spectra of OH-stretching mode have been studied in single samples of the protonic conductor, SrZrO₃:M³⁺ (M³⁺ = Sc³⁺, Y³⁺, Yb³⁺, Er³⁺). Four absorption bands, which correspond to four different sites of protons, are observed in IR spectra. Proton dynamics in these sites are studied by the annealing time dependence of IR spectra, which are quenched from high temperature. We have found that the relative population of protons among different sites changes as the proton concentration changes the crystal. This result indicates that the trapping energy for protons is different among these sites.
