Relationship between Phonon Parameters and Oxygen Ion Conductivity for Al-Yb Co-Doped Zirconia
Abstract:
The relationship between the optical phonon parameters and the oxygen ion conductivities were investigated for AlYb co-doped zirconia ceramics. Intrinsic intragrain ion conductivity, σdc, decreased with increasing Al loading into ytterbia-stabilized zirconia, while the damping parameter of the lattice vibration, γ1TO, increased. This phenomenon agreed with findings of our previous study, which revealed a relationship between the σdc and the γ1TO for zirconia-based ion conductors.
