Advances in Halide Perovskites for Photon Radiation Detectors

Abstract Halide perovskites possess remarkable properties, including a tunable bandgap, cost‐effective solution‐based synthesis, defect tolerance, and strong X‐ray stopping power, making them highly promising for next‐generation ionizing radiation detectors. Their exceptional sensitivity and ability to operate at low dose rates attract significant research interest. Moreover, the structural flexibility and diverse chemical compositions of halide perovskites provide distinct advantages over conventional inorganic scintillators, allowing for enhanced optimization of scintillation performance. In this short review, recent advancements in four key halide perovskite material systems are summarized and their performance is compared while examining their respective advantages and limitations. These systems include organic–inorganic hybrid lead halide perovskites, inorganic lead halide perovskites, lead‐free double perovskites, and lead‐free vacancy‐ordered double perovskites and their derivatives. Finally, potential applications are discussed and provide an outlook on the future of perovskite‐based photon radiation detectors.
