“…We note that four anions were arranged as terminals and the other two served as a bridge between two neighboring BiBr 6 octahedrons, inferring the corner shared packing 1D zigzag chain-type arrangements separated by the respective organic ligand cations. This structural order is comparable to the previous work by Zhang et al, Ji et al, and other work. ,, …”

Rational design is an important approach to consider in the development of low-dimensional hybrid organic−inorganic perovskites (HOIPs). In this study, 1-butyl-1-methyl pyrrolidinium (BMP), 1-(3aminopropyl)imidazole (API), and 1-butyl-3-methyl imidazolium (BMI) serve as prototypical ionic liquid components in bismuth-based HOIPs. Element-sensitive X-ray absorption spectroscopy measurements of BMPBiBr 4 and APIBiBr 5 reveal distinct resonant excitation profiles across the N Kedges, where contrasting peak shifts are observed. These 1D-HOIPs exhibit a large Stokes shift due to the small polaron contribution, as probed by photoluminescence spectroscopy at room temperature. Interestingly, the incorporation of a small fraction of tin (Sn) into the APIBiBr 5 (Sn/Bi mole ratio of 1:3) structure demonstrates a strong spectral weight transfer accompanied by a fast decay lifetime (2.6 ns). These phenomena are the direct result of Sn-substitution in APIBiBr 5 , decreasing the small polaron effect. By changing the active ionic liquid, the electronic interactions and optical responses can be moderately tuned by alteration of their intermolecular interaction between the semiconducting inorganic layers and organic moieties.

Organic−inorganic hybrid perovskites (OIHPs) have received particular attention due to their characteristic structural tunability and flexibility. These features make OIHPs behave with excellent modifications on macroscopic properties, such as ferroicity or semiconductor performances, etc. Herein, we report two 2D hybrid stibium-based halide perovskite (C 3 H 7 N) 3 Sb 2 X 9 (X = Br, 1; Cl, 2) ferroelastic semiconductor possessing dual switching properties of dielectric and second harmonic generation (SHG). Notably, these two hybrids exhibit halogen-regulated ferroelasticity and semiconductor properties. There is a significant difference in Curie temperature (T c ) and Xray radiation detection sensitivity (S), i.e., the ΔT c and ΔS are 38 K and 87 μC Gy air −1 cm −2 , respectively. Meanwhile, crystals 1 and 2 do not show dark current drift in cyclic measurements of different radiation doses with stable switching ratios of 30 and 10, separately. Meanwhile, these results were proven by scientific experimental results and density functional theory (DFT) calculations. Our work presents a facile and practical method to regulate macroproperties on the molecular level, providing a new vision to develop hybrid perovskite ferroic-photoelectric materials.

“…Along with the development of nontoxic perovskites and their derivatives, metal hybrid halides had the potential to be used in light emission diodes (LEDs) owing to their high photoluminescence quantum yields (PLQYs), broad-band emission, and long decay times. − Specifically, low-dimensional hybrid halides exhibit excellent photoluminescence properties with potential applications in X-ray scintillation. , Especially, Cu + -, Sb 3+ -, and Mn 2+ -based zero-dimensional (0D) halides have been designed as potential candidates for highly efficient and environmentally friendly scintillators due to their excellent light yield and high-energy radiation absorption performance. For instance, Xia et al reported a Mn 2+ -doped Cs 2 ZnBr 4 crystal with excellent scintillation performance, whose light yield reached about 15,600 photons MeV –1 and the detection limit was as low as 1.16 μGy air s –1 .…”

The increasing demands in optoelectronic applications have driven the advancement of organic−inorganic hybrid metal halides (OIMHs), owing to their exceptional optical and scintillation properties. Among them, zero-dimensional (0D) low-toxic manganese-based scintillators have garnered significant interest due to their exceptional optical transparency and elevated photoluminescence quantum yields (PLQYs), making them promising for colorful lightemitting diodes and X-ray imaging applications. In this study, two OIMH single crystals of (Br-PrTPP) 2 MnBr 4 (Br-PrTPP = (3bromopropyl) triphenylphosphonium) and (Br-BuTPP) 2 MnBr 4 (Br-BuTPP = (4-bromobutyl) triphenylphosphonium) were prepared via a facile saturated crystallization method. Benefiting from the tetrahedrally coordinated [MnBr 4 ] 2− polyhedron, both of them exhibited strong green emissions peaked at 517 nm owing to the d−d electron transition of Mn 2+ with near-unity PLQYs of 99.33 and 86.85%, respectively. Moreover, benefiting from the high optical transparencies and remarkable luminescence properties, these manganese halides also exhibit excellent radioluminescent performance with the highest light yield of up to 68,000 photons MeV −1 , negligible afterglow (0.4 ms), and linear response to X-ray dose rate with the lowest detection limit of 45 nGy air s −1 . In X-ray imaging, the flexible film made by the composite of (Br-PrTPP) 2 MnBr 4 and PDMS shows an ultrahigh spatial resolution of 12.78 lp mm −1 , which provides a potential visualization tool for X-ray radiography.
