Abstract Metal halide perovskites are revolutionizing X‐ray detection through a combination of low cost, solution processing, favorable optoelectronic properties, and high stopping power for high‐energy ionizing radiation. While perovskite single crystals polycrystalline wafers considered direct converters, most medical applications based on scintillators that shift radiation into the visible. Several materials market, but demonstrations CsPbBr 3 nanocrystals, possibly embedded in matrix material or combined with organic molecules as luminescent species, highlight their competitiveness established terms radioluminescence yield transient behavior. Major hurdles nanocrystal must overcome environmental stability toxicity. there still few examples high‐performance lead‐free scintillators, microcrystalline emerging promising reduced toxicity, significant Stokes shifts to avoid reabsorption emission thick films. Thus, near future scintillator will primarily be adoption recipes proven properties form. The colloidal solutions facilitate large‐scale printing homogeneous scattering‐free films obtain contrast spatial resolution images by scintillation.

Lead halide perovskite materials exhibit excellent scintillation performance, which, however, suffer from serious stability and toxicity problems. In contrast, the heavy metal-free anti-perovskite [ MX4 ] XA3 (A = alkali metal; M transition X Cl, Br, I), a class of electron-inverted derivatives, robust structural photophysical stability. Here, we design prepare lead-free MnBr4 BrCs3 nanocrystal (NC)-embedded glass for efficient X-ray-excited luminescence with high-resolution X-ray imaging spatial resolution 19.1 lp mm − 1. Due to unique crystal structure protection matrix, Cs3MnBr5 NC-embedded exhibits irradiation stability, thermal water resistance. These merits enable demonstration real-time durable radiography based on developed glassy composite. This work could stimulate research development novel metal open new path future in field ultrastable imaging.

Abstract X‐ray detection is vital in various fields such as medical imaging, security screening, and materials analysis. However, to meet the diverse requirements across different scenarios, current scintillators used for encounter challenges both immediate delayed radiation detections. In this work, flexibly controlling trap distribution through extra ions doping into Cs 2 NaTbCl 6 lead‐free perovskites presents a promising avenue addressing these advancing dose capabilities scientific domains. By Sb 3+ host, traps are significantly passivated improved crystallinity, resulting suppression of afterglow behaviors endowing high‐resolution real‐time dynamic detection. Additionally, incorporation Mn 2+ matrix causes significant lattice distortion, leading increased concentrations shallow deep traps, effectively boosting efficiency. This work may provide an effective strategy constructing efficient realization multi‐environmental imaging.
