However, achieving effective multicolor luminescence modulation and 3D patterning remains a challenge. This study introduces a Mn²⁺/Sb⁵⁺ charge compensation mechanism to induce purple photochromism in gallium silicate glass via the Mn²⁺ → Mn³⁺ transition under 532 nm laser irradiation. The effect is fully reversible, with efficient thermal erasure. By codoping Tb³⁺ and Mn²⁺, wavelength-independent red and green luminescence modulation enables multidimensional optical encoding. Arbitrary 3D photochromic patterns are directly inscribed using a 532 nm laser and decoded via tunable luminescence. This multimodal system advances 4D optical storage by combining 3D spatial dimensions with tunable luminescence intensity multiplexing. Mn²⁺/Tb³⁺ doped gallium silicate glass represents a breakthrough for 3D information display, data encryption, and insights into photochromic mechanisms in transition-metal-doped photonic systems.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"51 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The attenuate coordination between CD and ammonium at the supramolecular interface facilitates the nucleation rate, and the multisite interaction in different spatial directions retards their crystal growth, resulting in denser and defect-less tin perovskite films.

This stress arises from both electrochemical sources, due to lithium electrodeposition, and mechanical sources, such as external stack pressure. Solid electrolyte surface roughness and the applied stack pressure together affect stress development. This study combines electrochemical experiments, 3D synchrotron imaging, and mesoscale modeling to explore how stack pressure influences failure mechanisms in lithium free solid-state batteries. At low stack pressure, irregular lithium plating and the resulting high local current density drive failure. At higher stack pressure, uniform lithium plating is favored; however, notch-like features in the surface of the solid electrolyte experience high tensile stress, leading to fractures that cause premature short-circuiting.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"11 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular dynamics simulations reveal that lithium disordering at elevated temperatures significantly reduces the activation energy in Li₂MgCl₄. To stabilize this disorder at lower temperatures, we experimentally explored the Li_<i>x</i>Zr_{1–<i>x</i>/2}Mg_<i>x</i>/2Cl₄ system and found that Zr doping induces both Zr and Li disorder at the 16c site at room temperature (RT).

However, achieving WBG perovskites with a bandgap of 1.65 eV typically requires a Br-rich composition, which often results in severe light-induced I–Br phase segregation. In this work, a Cs-rich composition, FA_0.5Cs_0.5Pb(I_0.93Br_0.07)₃ perovskite with a bandgap of 1.65 eV, was studied and an arylformamidium additive-assisted approach was adopted to regulate the crystallization process of the intermediate phase. The arylformamidium molecules selectively adsorb onto the Cs₂PbI₂Cl₂ intermediate grains, inhibiting the interplay between DMSO and Cs₂PbI₂Cl₂, significantly increasing the grain size of intermediate-phase Cs₂PbI₂Cl₂ and improving its crystallinity. The highly uniform Cs₂PbI₂Cl₂ intermediate grains enhance the nucleation consistency and growth uniformity of the perovskite, ultimately forming a homogeneous perovskite film with large grain sizes and preferential orientation, while reducing the defect state densities. As a result, the 2-thienformamidium iodide (TFAI)-modified WBG perovskite solar cells achieved a power conversion efficiency (PCE) of 21.94%, alongside an impressive open-circuit voltage of 1.27 V. Moreover, the devices retained over 90% of their initial PCE after &gt;1000 h of maximum power point (MPP) tracking degradation testing, and negligible phase segregation was detected after 450 h of AM 1.5G illumination.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"33 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143444011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
