Low-dimensional organic–inorganic hybrid metal halides, with broadband luminescence, have attracted much attention for optoelectronic applications due to their rich in structural diversity and solution processibility. However, it is still unclear about how the solvent molecules influence properties of processed low-dimensional halides. Here, we prepared five different antimony-based crystal structures, [SbCl6]3- as halide octahedron 4, 4-difluoropiperidine (DFPD+) organic cation, by using solvents: hydrochloric acid (HCl) aqueous four solvents (dimethylformamide (DMF), methanol (MeOH), acetonitrile (ACN) dimethylacetamide (DMAC)). We revealed relation between structures optical properties, found participation structure causes significant lattice distortions, which beneficial achieving self-trapped exciton (STE) emission. Among them, (DFPD)6SbCl9·2DMAC exhibits a remarkable photoluminescence (PL) quantum yield approximately 90 %. The STE dynamics were characterized femtosecond transient absorption time-resolved PL spectroscopies. Simultaneously, this study also provides new directions expanding application luminescent halides: addition UV-LEDs, efficient rapid detection or can be achieved raw materials, while realizing potential multi-level anti-counterfeiting.

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.

Two-dimensional (2D) metal-halide perovskites with highly efficient room-temperature phosphorescence (RTP) are rare due to their complex structures and intricate intermolecular interactions. In this study, by varying the alkyl chain length in organic amines, we synthesized two 2D perovskites, namely 4-POMACC 4-POEACC, both of which exhibit significant RTP emission. Notably, demonstrates a stronger green emission significantly longer lifetime (254 ms) higher photoluminescence quantum yield (9.5%) compared 4-POEACC. A thorough investigation structural optical properties reveals that shorter chains can enhance performance reduced molecular vibrations more effective exciton recombination. Computational calculations further show smaller energy gap between S1 Tn 4-POMA facilitates intersystem crossing, thereby improving performance. Based on remarkable properties, demonstrated applications information encryption. This work offers novel design strategy could inspire development next-generation materials.

Low-dimensional organic–inorganic hybrid perovskites (OIHPs) have shown significant potential in the optoelectronic field due to their adjustable structure and properties. However, poor air stability flexibility of OIHP crystals limit further development. Herein, three been synthesized using cadmium chloride isomer phenylenediamine as raw materials. Mn2+ doping turns on red-light emission Cd-based OIHPs at around 625 nm. Interestingly, organic ligands with different steric hindrance can induce a transition from two dimensions (2D) one dimension (1D), thereby regulating quantum yield red luminescence range 38.4% nearly 100%. It is found that surface-exposed amino groups are easy oxidize, resulting instability these crystals. Therefore, poly(lactic acid) (PLA) selected passivate through hydrogen bonding between C═O PLA –NH2 surface OIHPs. As result, production OIHP-based flexible films highly efficient stable be obtained after being encapsulated by PLA. They demonstrate enormous application X-ray imaging. This study not only realizes perovskite but also provides an effective design idea for scintillators.
