摘要

透明铁电陶瓷由于其耦合光学和电学性质的能力而广受欢迎。然而，同时实现陶瓷的高电学和光学性能仍然是一个艰巨的挑战。采用两步烧结工艺结合稀土掺杂策略，制备了xLa-24PIN-42PMN-34PT透明压电陶瓷，实现了已知最高d33 (>1000 pC/N)，优异的透光率（1600 nm处T = 66.2%），接近TC时压电性能仅下降26.8%。PFM和原位XRD结果表明，La3+掺杂诱导的平行条纹状和水印状共存铁电畴结构产生了较大的压电响应。铁电畴结构的小尺寸减小了光散射损耗。由四方主导的取向相结构保证了优异的热稳定性。本研究为后续制备高性能透明铁电陶瓷提供了有价值的思路。

Enhanced piezoelectricity and temperature stability in La-doped PIN-PMN-PT transparent ceramics by composition regulation

Transparent ferroelectric ceramics are popular due to their ability to couple optical and electrical properties. However, simultaneously achieving high electrical and optical performance in ceramics remains a formidable challenge. By using the two-step sintering process combined with a rare earth doping strategy, xLa-24PIN-42PMN-34PT transparent piezoelectric ceramics were prepared, achieving the coexistence of the highest known d33 (>1000 pC/N), excellent transmittance (T = 66.2% at 1600 nm), and the piezoelectric properties decrease by only 26.8% when approaching TC. PFM and in situ XRD results indicate that the parallel stripe-like and watermark-like coexisting ferroelectric domain structures, which are induced by La3+ doping, generate large piezoelectric responses. Light scattering loss is reduced by the small size of the ferroelectric domain structure. Excellent thermal stability is ensured by the tetragonal-dominated morphotropic phase structure. This work provides a valuable idea for the subsequent preparation of transparent ferroelectric ceramics with high performance.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
