Halide perovskite scintillators for X-ray detection: from structure to engineering

). We also discuss the fabrication of composite scintillating screens using polymer and glass matrices, and explore nanostructured systems offering enhanced flexibility, stability, and spatial resolution. Finally, we address key challenges, such as toxicity, scalability, and long-term stability, and outline promising future directions, including the development of multifunctional scintillators, the engineering of materials for photon-counting detectors, the application of emerging paradigms like supramolecular chemistry and nanophotonics, and advancements in data-driven discovery and machine learning technologies.
