Abstract

<abstract abstract-type="main" id="jace12847-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Lead‐free single crystal (Na_1/2Bi_1/2)TiO₃–1.5 at.%Bi(Zn_1/2Ti_1/2)O₃ (NBT–1.5BZT) with dimension of Φ35 mm × 12 mm was successfully grown by a top‐seeded solution growth technique. The average and local structure were studied by a combination of X‐ray diffraction and Raman spectroscopy. The electric and optical properties of &lt;001&gt;‐oriented single crystals were investigated systematically. Compared with pure NBT, the piezoelectric constant and transmission coefficient were both enhanced, that is, from 62 pC/N and ~60% to 121 pC/N and ~70%, respectively. Furthermore, domain structure observation suggested that the &lt;110&gt;‐oriented tetragonal ferroelastic domains in NBT were suppressed at room temperature with addition of BZT, which was responsible for the improved piezoelectric and optical properties of NBT–1.5BZT single crystal.</p> </abstract>
