Abstract
A series of regular shaped Pb(Zn1/3Nb2/3)O3‐based ternary ferroelectric single crystals (1 − x)Pb(In1/2Nb1/2)O3–0.33Pb(Zn1/3Nb2/3)O3–xPbTiO3 (PIN–PZN–PT) have been grown by means of the top‐seeded solution growth method that prevented pyrochlore phase and promoted [001] or [111] growth. The nucleation and crystallization behavior of the Pb(Zn1/3Nb2/3)O3‐based ferroelectric single crystals differed from other relaxor‐based ferroelectric single crystals was discovered. Di‐/piezo‐/ferro‐/pyroelectric properties were characterized systematically. The PIN–PZN–PT single crystals showed large coercive fields Ec, high Curie temperature TC and high pyroelectric coefficient P, presenting similar performance but better thermal stability compared with the PZN–PT single crystals, and making it a promising material for transducers and IR detectors in a wider temperature range.
