中國粉體網(wǎng)訊 透明鐵電材料可以將光學功能與壓電效應耦合在一起，為光聲成像系統(tǒng)、透明壓電致動器、透明機器人等提供關(guān)鍵材料。然而，壓電性、透明性和居里溫度之間的相互制約關(guān)系使得制備同時具有高居里點、高透明度和高壓電性的鐵電材料非常困難，這阻礙了其在多功能耦合器件領(lǐng)域的應用。
近日，青島大學物理科學學院制備出Sm摻雜PIN-PMN-PT透明鐵電陶瓷。其居里溫度Tc~179 ℃、壓電系數(shù)d33~905 pC/N、電光系數(shù)r~814 pm/V、近紅外波段透光率63%，綜合性能優(yōu)異。與PMN-PT基透明陶瓷（Tc約100℃）相比，PIN-PMN-PT透明陶瓷在壓電性能的溫度穩(wěn)定性方面表現(xiàn)優(yōu)異。并且基于該透明陶瓷的電光效應和壓電效應，實現(xiàn)了電光信息調(diào)制和能量轉(zhuǎn)換。相關(guān)成果以"Sm-doped PIN-PMN-PT transparent ceramics with high Curie temperature, good piezoelectricity, and excellent electro-optical properties"為題發(fā)表在ACS Applied Materials & Interfaces上。青島大學物理科學學院2019級碩士研究生鄭鳳基為該論文第一作者，青島大學張永成副教授為論文的通訊作者。
這一成果也是該團隊在前期關(guān)于高電光性能PMN-PT透明陶瓷(Advanced Optical Materials, 9, 2002139 (2021))和高壓電性能PMN-PT透明陶瓷（ACS Appl. Mater. Interfaces, 13, 54210-54216(2021)）研究基礎(chǔ)上取得的新進展。上述工作得到了國家自然科學基金、山東省自然科學基金的支持。
