Abstract Low-dimensional lead-free metal halide perovskites are highly attractive for cutting-edge optoelectronic applications. Herein, we report a class of scandium-based double perovskite crystals comprising antimony dopants that can generate multiexcitonic emissions in the ultraviolet, blue, and yellow spectral regions. Owing to zero-dimensional nature crystal lattice minimizes energy crosstalk, different excitonic states be selectively excited by ultraviolet light, X-ray irradiation, mechanical action, enabling dynamic control steady/transient-state features modulating excitation modes. Remarkably, transparent exhibits efficient white photoluminescence (quantum yield >97%), blue emission with long afterglow (duration >9 h), high-brightness self-reproducible violet-blue mechanoluminescence. These findings reveal exceptional capability low-dimensional integrating various luminescence, offering exciting opportunities multi-level data encryption all-in-one authentication technologies.

Abstract Recently, Sb 3+ ‐activated 0D Zr(IV)‐based metal halides have gained enormous attention for their unique optical properties. However, realizing efficient white emission and multiple reversible emissions in a single system remains great challenge. Parallelly, the currently reported organic are mainly through aimless regulation of type A‐site cations, severely limiting development. Herein, all‐inorganic Cs 2 ZrCl 6 :Sb is employed as conformational model, three different compounds ‐doped [18‐crown‐6@A] (A = K, Rb, Cs) developed via supramolecular assembly. All show tunable with luminous efficiency 91.28% [18‐crown‐6@K] , 84.84% [18‐crown‐6@Rb] 78.63% [18‐crown‐6@Cs] which shall stem from ‐induced multi‐exciton [SbCl ] 3− octahedron. Particularly, strong interaction can enhance structural rigidity suppress nonradiative transitions, dominated reason exhibits emission.

Low-dimensional organic-inorganic hybrid metal halide materials have attracted widespread attention due to their excellent and tunable photoelectric properties. However, the low intrinsic photoluminescence quantum yields (PLQYs) limit further applications in optoelectronic devices. Here, we report synthesis of lead-free zero-dimensional indium chloride crystals, (FA)3InCl6: xSb3+, with strong red-light emission through controlled Sb3+ doping. The optimal composition, 20.16% Sb3+, exhibits PLQY up 30% emits red broadband light centered at 690 nm. enhancement doped samples was investigated by combining temperature-dependent wavelength-dependent spectra, revealing self-trapped exciton (STE) recombination process. clear elucidation complexation process has provided a solid theoretical basis for optimization material properties, which is great significance development new light-emitting materials.

Lead-free metal halides with tunable structures have emerged as a new class of optoelectronic materials. The arrangement halide polyhedra defines their structural dimensionality and serves key factor influencing optical properties. To investigate this, we synthesized four different antimony (Sb)-doped indium (In)-based halides, all which possess zero-dimensional (0D) electronic but exhibit 3D, 2D, 1D, 0D at the molecular level. With decreasing dimensionality, self-trapped exciton (STE) emission shows red shift peak position from 496 to 663 nm. We revealed that is caused by increased distortion [SbCl

Abstract Zero‐dimensional (0D) metal halides are attractive due to their structure‐dependent and tunable photoluminescence properties. Herein, a new 0D organic–inorganic hybrid Zn‐based halide, (C 4 H 12 N 2 )ZnBr , featuring long‐term stable crystal structure moisture‐stable PL emission under various extreme conditions is reported. A strong electron–phonon coupling effect enables the halide display highly efficient blue light at 472 nm with large Stokes shift of 7385 cm −1 . Intriguingly, heterovalent substitution Cu + ‐Zn 2+ further enhances quantum efficiency 60% as introduction effectively suppresses nonradiative recombination process. Besides, formation twisted [SbBr ] − tetrahedra via Sb 3+ help achieve broadband near‐infrared (NIR) (760 nm) full width half maxima (FWHM) 203 nm, enabling potential applications in night‐vision nondestructive fruit damage inspection. Detailed structural optical analyses used investigate photophysical processes different self‐trapped exciton (STE) for pristine /Sb ‐doped halides.

Abstract Low‐dimensional lead‐free metal halide perovskites have attracted considerable attention for the development of multifunctional optoelectronic materials owing to their extensive structural diversity and adjustable optical properties. However, organic cation‐based low‐dimensional halides often exhibit limited thermal stability, while inorganic cations‐based ones a poor solution processability. To address these challenges, this study proposes hybrid organic–inorganic cation approach by utilizing both 4,4‐difluoropiperidine (DFPD) cesium (Cs + ) prepare halides: 2 CsInCl 6 . Two isostructural are developed: α‐(DFPD) β‐(DFPD) , which different space group symmetries. This strategy ensures stability introduces diversity. Doping with antimony (Sb 3+ enhances its PLQY from 0% 100%. The emission centers temperature‐insensitive behavior maintain efficient stable PL even at high temperatures (up 400 K), making them excellent candidates as thermally phosphor solid‐state lighting applications. work thus expands scope developing halides.
