摘要

透明铁电陶瓷作为一种新型的光电多功能耦合材料，在光存储和智能窗口方面具有巨大的应用潜力。然而，通过操纵制备工艺、微观结构和相结构来实现高透明度提出了相当大的挑战。在这里，我们采用多种策略，包括制备工艺调节和在K0.5Na0.5NbO3的a位掺杂La3+和Tb3+，以制备出具有透明度、光致变色和光致发光多模式可逆调制的特殊透明陶瓷。本研究为透明多功能材料的设计提供了一个新的视角。

Photochromic and luminescent modulation behaviors in K0.5Na0.5NbO3-based ferroelectric transparent ceramics

Transparent ferroelectric ceramics, emerging as innovative photoelectric multifunctional coupling material, demonstrate significant potential for applications in optical storage and smart windows. However, achieving high transparency via manipulation of the preparation process, microstructure, and phase structure poses a considerable challenge. Here, we employ multiple strategies, including the fabrication technology regulation and donor doping of La³⁺ and Tb³⁺ at the A-site of K_0.5Na_0.5NbO₃ to fabricate exceptional transparent ceramics coupled with multi-mode reversible modulations of transparency, photochromism, and photoluminescence. This research offers a novel perspective on the design of transparent multifunctional materials.
