Multifunctional transparent ferroelectric ceramics have widespread applications in electro-optical devices. Unfortunately, almost all currently used electro-optical ceramics contain a high lead concentration. In this work, via coupling of spark plasma sintering with high pressure, we have successfully synthesized bulk lead-free transparent nanostructured BaTiO(3) (abbreviated as BTO) and SrTiO(3) (STO) ceramics with excellent optical transparency in both visible and infrared wavelength ranges. This success highlights potential ingenious avenues to search for lead-free electro-optical ceramics.
多功能透明铁电陶瓷在电光器件中有广泛的应用。遗憾的是,目前几乎所有使用的电光陶瓷都含有较高浓度的铅。在这项工作中,我们通过结合火花等离子烧结和高压技术,成功地合成了块状无铅透明纳米结构 BaTiO(3)(简称 BTO)和 SrTiO(3)(简称 STO)陶瓷,它们在可见光和红外波长范围内都具有优异的光学透明度。这一成功为寻找无铅电光陶瓷提供了潜在的巧妙途径。
