中国粉体网讯 透明铁电材料可以将光学功能与压电效应耦合在一起，为光声成像系统、透明压电致动器、透明机器人等提供关键材料。然而，压电性、透明性和居里温度之间的相互制约关系使得制备同时具有高居里点、高透明度和高压电性的铁电材料非常困难，这阻碍了其在多功能耦合器件领域的应用。
近日，青岛大学物理科学学院制备出Sm掺杂PIN-PMN-PT透明铁电陶瓷。其居里温度Tc~179 ℃、压电系数d33~905 pC/N、电光系数r~814 pm/V、近红外波段透光率63%，综合性能优异。与PMN-PT基透明陶瓷（Tc约100℃）相比，PIN-PMN-PT透明陶瓷在压电性能的温度稳定性方面表现优异。并且基于该透明陶瓷的电光效应和压电效应，实现了电光信息调制和能量转换。相关成果以"Sm-doped PIN-PMN-PT transparent ceramics with high Curie temperature, good piezoelectricity, and excellent electro-optical properties"为题发表在ACS Applied Materials & Interfaces上。青岛大学物理科学学院2019级硕士研究生郑凤基为该论文第一作者，青岛大学张永成副教授为论文的通讯作者。
这一成果也是该团队在前期关于高电光性能PMN-PT透明陶瓷(Advanced Optical Materials, 9, 2002139 (2021))和高压电性能PMN-PT透明陶瓷（ACS Appl. Mater. Interfaces, 13, 54210-54216(2021)）研究基础上取得的新进展。上述工作得到了国家自然科学基金、山东省自然科学基金的支持。
