(K,Na)NbO3 ferroelectrics: A new class of solid-state photochromic materials with reversible luminescence switching behavior

Abstract

In this paper, we reported a kind of new photosensitive material: Sm doped K0.5Na0.5NbO3 (KNN) ceramics, fabricated by the solid-sate reaction method, which exhibits both photochromism and luminescent switching properties. By alternating visible light irradiation (λ>407 nm) and thermal stimulus, the samples show a reversible color change from initial green to pale gray. Interestingly, luminescent emission intensity can be effectively tuned upon photochromic reactions. Furthermore, the luminescent switching degree strongly depends on the firing temperature. These results suggest that KNN-based perovskite oxides with photochromism, luminescent switching and ferroelectric energy storage properties are particularly attractive for optical data storage applications as multi-functional materials.
