Abstract: 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 K0.5Na0.5NbO3 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. [ABSTRACT FROM AUTHOR]
