Summary: Low-dimensional hybrid antimony halide perovskites have excellent photoluminescence behaviors, but optimizing the luminescence performance through molecule-level structural regulation is still a challenge. In this work, three hybrid antimony halides with broadband yellow-light emissions were successfully synthesized using the solution evaporation method. These antimony halides exhibit self-trapped excitons (STEs) as the origin of the broadband light emissions, and they have the potential to be used as yellow-light emitting materials and white LEDs.

Summary: This study investigates the weak interlayer coupling and unclear mechanism in layered hybrid silver bismuth bromine (LH-AgBiBr), which limit its X-ray detection sensitivity and stability. The design rules for LH-AgBiBr and its influence on X-ray detection performance are reported for the first time. By appropriately designing the divalent amine, improved interlayer coupling and reduced micro strain are achieved, leading to enhanced crystal stability and mechanical hardness. The optimized parallel device based on BDA2AgBiBr8 demonstrates record sensitivity and ultra-low detection limit, outperforming other reported LH-AgBiBr X-ray detectors. Moreover, the device exhibits remarkable endurance against moisture, thermal, and radiation effects. High-resolution hard X-ray imaging is successfully demonstrated using linear detector arrays. These findings provide valuable guidelines for future materials design and device optimization.

Summary: Hydrogen-bonded organic frameworks (HOFs) are a new class of porous crystalline materials assembled by hydrogen bonds. They offer advantages such as mild synthesis, easy purification, and good recyclability. Enhancing stability, establishing porosity, and functionalization are the main challenges in HOFs development. Recently, more stable and permanently porous HOFs, including hybrid HOFs with stronger charge-assisted hydrogen bonds and coordination bonds, have been reported.

Summary: Organic-inorganic hybrid metal halides with emissive organic cations are studied by assembling emissive organic cations with different metal-chloride anions to form new single crystal phases. The photoluminescence properties of the metal halides, such as FWHM and PLQY, are influenced by strong inter- and intramolecular interactions, resulting in a restraining effect and increased rigid degree of the organic cations in bulk single crystals. This work clarifies the photophysical properties of the organic cations and paves the way for further study of organic-inorganic hybrid metal halides materials with different luminescence mechanisms.

Summary: A new multicationic structurally disordered K5FeHf(MoO4)(6) crystal belonging to the molybdate family is synthesized and its electronic and vibrational properties are characterized. The vibrational spectra are dominated by the MoO4 tetrahedra vibrations, while the lattice modes are observed in a low-wavenumber part of the spectra. The compound exhibits paramagnetic behavior with dominant antiferromagnetic interactions and has direct and indirect optical bandgaps of 2.97 and 3.21 eV, respectively. The narrowing of the bandgap is explained by the presence of Mott-Hubbard optical excitation in the system of Fe3+ ions.
