摘要

The dielectric functions and phase transitions of MgO modified Pb _0.99 (Zr _0.95 Ti _0.05 ) _0.98 Nb _0.02 O ₃ (PZTN-x wt% MgO, x = 0, 0.1, 0.2, 0.5) ceramics have been investigated using temperature-dependent spectroscopic ellipsometry. With the aid of standard critical-point (SCP) model, four typical interband transitions can be observed from the second derivative of dielectric functions. Three transition process are observed and can be linked to antiferroelectric (AFE)-ferroelectric (FE) (T ₁ ∼ 250 K), low temperature ferroelectric phase [FE _R(LT) ]to high temperature one [FE _R(HT) ] (T ₂ ∼ 300 K), and ferroelectric-paraelectric phase (T _C ∼ 500 K).
