Luminescent tunable materials have promising application potential in optical switches, optical information storage, and so on. Although europium (Eu) is a good downconversion red luminescent rare earth element, there are few studies on the upconversion luminescence and photochromism of Eu-doped potassium sodium niobate (KNN) ferroelectrics. In this paper, Eu 3+ and Yb 3+ codoped KNN translucent ferroelectric ceramics were synthesized and the effect of Yb 3+ content on the luminescence and photochromism is studied. Both the up-and downconversion luminescence intensity and decay rate before and after photochromism can be well controlled by Yb 3+ content. That is, an upconversion luminescent translucent ceramic that can be completely discolored by 405 nm light illumination for 10 s was obtained. The luminescence modulations are closely related to the evolution of oxygen vacancy and crystal field around the luminescence center, which can be verified by the illumination-induced electron paramagnetic resonance (EPR) signal and local piezoresponse switching behavior variation as well as the discovery of energy level splitting and spectral line shift. We believe that this work shows a paradigm for designing high-performance reversible multimode luminescence modulation ferroelectric ceramics.

Eco‐friendly transparent dielectric ceramics with superior energy storage properties are highly desirable in various transparent energy‐storage electronic devices, ranging from advanced transparent pulse capacitors to electro‐optical multifunctional devices. However, the collaborative improvement of energy storage properties and optical transparency in KNN‐based ceramics still remains challenging. To address this issue, multiple synergistic strategies are proposed, such as refining the grain size, introducing polar nanoregions, and inducing a high‐symmetry phase structure. Accordingly, outstanding energy storage density (Wtotal ≈7.5 J cm−3, Wrec ≈5.3 J cm−3) and optical transmittance (≈76% at 1600 nm, ≈62% at 780 nm) are simultaneously realized in the 0.94(K0.5Na0.5)NbO3‐0.06Sr0.7La0.2ZrO3 ceramic, together with satisfactory charge‐discharge performances (discharge energy density: ≈2.7 J cm−3, power density: ≈243 MW cm−3, discharge rate: ≈76 ns), surpassing previously reported KNN‐based transparent ceramics. Piezoresponse force microscopy and transmission electron microscopy revealed that this excellent performance can be attributed to the nanoscale domain and submicron‐scale grain size. The significant improvement in the optical transparency and energy storage properties of the materials resulted in the widening of the application prospects of the materials.
