Multifunctional photodetectors have driven the development of traditional optical communication technologies and emerging artificial intelligence fields. While three-dimensional (3D) organic lead trihalides recently demonstrated potential as versatile photodetectors, device performance is constrained by ion mobility limitations. In contrast, low-dimensional metal halide perovskites (MHPVKs) exhibit enhanced intrinsic stability, suppressed migration, exceptional photoelectric properties. Inspired these advantages, a zero-dimensional (0D) manganese (Mn)-based organic-inorganic hybrid (MA2MnBr4) fabricated high-quality films at room temperature via facile melt-growth method presented. Subsequently, Ultraviolet (UV) X-ray detectors based on MA2MnBr4 are fabricated, their systematically characterized. The UV photodetector an film showed response rate 11 mA W-1 detection 1.4 × 1012 Jones. Meanwhile, MA2MnBr4-based detector has high sensitivity 1959.9 µC Gyair -1 cm-2 exceptionally low dose 73.1 nGyair s-1, both which required for medical diagnosis. This study not only advances understanding Mn-based material but also highlights promise high-performance detection.

Abstract Rare earth‐doped glasses have attracted extensive attention due to their excellent luminescent property. It is of great significance for the development optical functional glass obtain unique properties through structural regulation. Here, via optimization, multicolor borosilicate with dual luminescence centers (Ce 3 ⁺ ions and oxygen vacancy defect) are obtained. Leveraging distinct traits these two centers, tunable colors ranging from purple orange–red achieved by varying excitation wavelength temperature. Under X‐ray excitation, exhibit one highest scintillation intensities (85.69% Bi 4 Ge O 12 crystal) among Ce 3+ ‐doped reported in recent years, imaging resolution (11 LP mm −1 ) comparable CsI:Tl crystal. Capitalizing on characteristics performance, a 3D anti‐counterfeiting scheme an model developed, demonstrating promising practical applications. After being stored under ambient conditions intensity retains more than 98% its initial value, underscoring exceptional stability glass. This work not only presents multifunctional material high‐level but also provides insights into design.

Abstract Metal‐organic frameworks (MOFs) glass is a newly invented hybrid materials with the unique optical response and great potential for photonic applications. Unfortunately, limited by high viscosity instability issue of ZIF‐62 precursor, controllable synthesis homogeneous MOFs remains significant challenge. In this manuscript, it found that reducing stoichiometric ratio between Zn ions ligand precursor can effectively suppress growth enable to obtain tiny particles. By using them, homogenous free bubbles be fabricated gentle heat‐treatment. This exhibits interesting response, including intense luminescence, atmosphere sensitive energy particle scintillating emission. The applications active sensing neutron detection extremely signal‐to‐noise 27.1 dB are demonstrated. results suggest amorphization may create new type material unprecedent application.
