Transparent piezoelectric materials are capable of coupling several physical effects such as optics, acoustics, electricity, and mechanical deformation together, which expands applications for mechanical-electro-optical multifunctional devices. However, piezoelectricity, transparency, and Curie temperature restrict each other, so it is difficult to achieve high piezoelectricity with both good transparency and a high Curie point. In this paper, Sm-doped 24Pb(InNb)O-42Pb(MgNb)O-34PbTiO (PIN-PMN-PT) transparent ceramic with a high piezoelectric coefficient of 905 pC/N, excellent electro-optical coefficient of 814 pm/V, and high Curie-point of 179 °C is fabricated. Sm doping effect on the phase structures, piezoelectricity, ferroelectricity, optical transparency, electro-optical properties, and thermal stability is systematically investigated. Compared with PMN-PT transparent ceramics, PIN-PMN-PT transparent ceramics exhibit better temperature stability. Electro-optical modulation and energy conversion are achieved using PIN-PMN-PT transparent piezoelectric ceramic, which indicates that it has great potential to develop mechanical-electrical-optical multifunctional coupling devices for optical communication, energy harvesting, photoacoustic imaging, and so on.
透明压电材料能够将光学、声学、电学和机械变形等多种物理效应耦合在一起，这拓展了机电光多功能器件的应用范围。然而，压电性、透明度和居里温度相互制约，因此很难同时实现高压电性、良好的透明度和高居里点。本文制备了具有905 pC/N的高压电系数、814 pm/V的优异电光系数和179℃的高居里点的Sm掺杂24Pb(InNb)O-42Pb(MgNb)O-34PbTiO（PIN-PMN-PT）透明陶瓷。系统研究了Sm掺杂对相结构、压电性、铁电性、光学透明度、电光性能和热稳定性的影响。与PMN-PT透明陶瓷相比，PIN-PMN-PT透明陶瓷表现出更好的温度稳定性。利用PIN-PMN-PT透明压电陶瓷实现了电光调制和能量转换，这表明它在开发用于光通信、能量收集、光声成像等的机电光多功能耦合器件方面具有巨大潜力。
