However, materials discovery and property optimization are typically time-consuming due to the limited throughput of traditional synthesis methods. In this work, we use a high-throughput combinatorial synthesis approach to fabricate lead-free ferroelectric superlattices and solid solutions of (Ba_0.7Ca_0.3)TiO₃ (BCT) and Ba(Zr_0.2Ti_0.8)O₃ (BZT) phases with continuous variation of composition and layer thickness. High-resolution x-ray diffraction (XRD) and analytical scanning transmission electron microscopy (STEM) demonstrate high film quality and well-controlled compositional gradients. Ferroelectric and dielectric property measurements identify the “optimal property point” achieved at the composition of 48BZT–52BCT. Displacement vector maps reveal that ferroelectric domain sizes are tunable by varying {BCT–BZT}_<i>N</i> superlattice geometry.

However, many SSEs, such as sulfides and hydrides, are highly sensitive to water, limiting their practical use. As one class of important perovskites, the Ruddlesden–Popper perovskite oxides (RPPOs), show great promise as SSEs due to their exceptional stability, particularly in terms of water resistance. In this review, the crystal structure and synthesis methods of RPPOs SSEs are first introduced in brief. Subsequently, the mechanisms of ion transportation, including oxygen anions and lithium-ions, and the relevant strategies for enhancing their ionic conductivity are described in detail. Additionally, the progress made in developing flexible RPPOs SSEs, which are critical for flexible and wearable electronic devices, has also been summarized. Furthermore, the key challenges and prospects for exploring and developing RPPOs SSEs in all-solid-state batteries are suggested.

The formation of Ag nanoclusters by light irradiation has been a significant development in the field of photochromic glass research. However, extending this approach to other metal nanoclusters remains a challenge. In this study, we present a pioneering method for crafting photochromic glass with reliably adjustable dual-mode luminescence in both the NIR and visible spectra. This was achieved by leveraging bimetallic clusters of bismuth, resulting in a distinct and novel photochromic glass. When rare-earth-doped, bismuth-based glass is irradiated with a 473 nm laser, and it undergoes a color transformation from yellow to red, accompanied by visible and broad NIR luminescence. This phenomenon is attributed to the formation of laser-induced (Bi⁺, Bi⁰) nanoclusters. We achieved reversible manipulation of the NIR luminescence of these nanoclusters and visible rare-earth luminescence by alternating exposure to a 473 nm laser and thermal stimulation. Information patterns can be inscribed and erased on a glass surface or in 3D space, and the readout is enabled by modulating visible and NIR luminescence. This study introduces a pioneering strategy for designing photochromic glasses with extensive NIR luminescence and significant potential for applications in high-capacity information encryption, optical data storage, optical communication, and NIR imaging.
