Abstract Organic manganese halides have gained attention as luminescent materials due to their characteristics, such low toxicity, ease of synthesis, and high photoluminescence quantum yield (PLQY). This study challenges the common belief that increasing Mn–Mn distance invariably boosts PLQY. It introduces a 3D diagram illustrating importance ground‐state excited‐state band alignments in influencing The research identifies how different organic cations result two distinct alignments, thus impacting Additionally, delves into effects temperature pressure on stability three bromides. Findings indicate structural attributes significantly influence materials' responses thermal stress pressure. For instance, (PPh4)2MnBr4, characterized by strong conjugation effect stable structure, displays superior resistance. Conversely, (N‐BHMTA) 2 MnBr 4 , with more intricate structure lower stability, exhibits susceptibility irreversible alterations under elevated These insights are pivotal for developing stable, efficient across diverse applications.

Abstract All‐inorganic metal halides have merged as auspicious materials for optoelectronic applications due to their predominant tunable and controlled photoluminescence (PL) properties. Despite substantial efforts advances in the development of these all‐inorganic halides, considerable long‐term challenges remain be solved realize cutting‐edge material performances. Here, an halide RbCdCl 3 , featuring a reversible structural phase transformation from non‐perovskite (orthorhombic‐phase) perovskite (tetragonal‐phase) structure is reported. Intriguingly, via regulation engineering, near‐unity quantum yield (PLQY) along with large Stokes shift (275 nm) long decay lifetime (14.69 ms) achieved :Mn 2+ thermochromic fluorescent materials, comparing pristine non‐pervoskite initial PLQY 3.1%. Moreover, underlying PL switching mechanisms are systematically elucidated by situ optical characterizations first‐principles calculations. This work demonstrates anti‐counterfeiting based on also provides engineering broaden manifold fields.

Stimulus-responsive inorganic–organic hybrid metal halides (IOMHs) have shown great potential in applications such as sensing and anti-counterfeiting. IOMHs can undergo a variety of structural changes when triggered by humidity; however, relevant reports dimensionality change from zero dimension (0D) to one (1D) are rare. This study investigates the synthesis, structure, properties two antimony-based IOMHs, namely 0D-(Mp)3SbCl6·MeCN 1D-(Mp)2SbCl5 (Mp = protonated morpholine; MeCN acetonitrile). Photophysical characterizations show that (Mp)3SbCl6·MeCN, being excited at 375 nm, exhibits typical self-trapped exciton triplet state broad-band emission, with peak 620 nm quantum yield high 75.06%. Under humid conditions, 0D structure (Mp)3SbCl6·MeCN undergoes phase transition, leading 1D (Mp)2SbCl5. transition is accompanied fluorescence quenching. X-ray powder diffraction, Raman spectroscopy, thermogravimetric analysis confirm process its reversibility. Based on contrast before after demonstrated an ideal material for water sensing, capable detecting trace amounts tetrahydrofuran detection limit 0.2% v/v.
