摘要

The relationship between the optical phonon parameters and the oxygen ion conductivities were investigated for Al-Yb co-doped zirconia ceramics. Intrinsic intragrain ion conductivity, σ_(dc), decreased with increasing Al loading into ytterbia-stabilized zirconia, while the damping parameter of the lattice vibration, γ_(1TO), increased. This phenomenon agreed with findings of our previous study, which revealed a relationship between the σ_(dc) and the γ_(1TO) for zirconia-based ion conductors.
