ABSTRACT
Phase transition and pyroelectric behaviors of Pb0.955La0.03(Zr0.42Sn0.40Ti0.18)O3 (PLZST) ceramics were investigated as functions of temperature and electric field. Pyroelectric coefficient about 160×10-8 C cm-2 K-1 is detected at the electric-field-induce ferroelectric (FEIN) to antiferroelectric phase transition for the poled samples. Reversible pyroelectric response with a pyroelectric coefficient maximum about 50×10-8 C cm-2 K-1 is obtained when a dc bias is applied on the depoled sample simultaneously.
