Abstract

Perovskite scintillators have emerged as one class of competitive scintillators for next-generation X-ray detection and imaging due to their unique properties, including high atomic number (Z), superior radiation absorption capability, high photoluminescence quantum yield (PLQY), ultrafast response time, excellent spatial resolution, and low-cost fabrication. The tunable structure and versatile chemical compositions of perovskite scintillators provide distinguishable advantages over traditional inorganic scintillators for optimizing scintillation performance. This review briefly outlines the historical development of scintillators and categorizes perovskite-based scintillators based on their structural characteristics, introducing key performance parameters and evaluation criteria. Recent progress is then summarized in three major application domains: high-resolution X-ray imaging, ultrafast dynamic imaging, and multi-energy spectral imaging. The discussion highlights representative achievements and technical challenges associated with light yield, temporal response, and image resolution. Finally, current research bottlenecks, such as poor environmental stability, fabrication complexity, and system integration issues, are examined, and potential strategies for future development are proposed, including material optimization, structural engineering, and interdisciplinary system-level integration. This review aims to provide a comprehensive understanding of perovskite scintillators and promote their practical implementation in advanced radiation detection technologies.

期刊介绍： The journal seeks to publish papers that present advances in the following areas: spontaneous and stimulated luminescence (including scintillating materials, thermoluminescence, and optically stimulated luminescence); electron spin resonance of natural and synthetic materials; the physics, design and performance of radiation measurements (including computational modelling such as electronic transport simulations); the novel basic aspects of radiation measurement in medical physics. Studies of energy-transfer phenomena, track physics and microdosimetry are also of interest to the journal. Applications relevant to the journal, particularly where they present novel detection techniques, novel analytical approaches or novel materials, include: personal dosimetry (including dosimetric quantities, active/electronic and passive monitoring techniques for photon, neutron and charged-particle exposures); environmental dosimetry (including methodological advances and predictive models related to radon, but generally excluding local survey results of radon where the main aim is to establish the radiation risk to populations); cosmic and high-energy radiation measurements (including dosimetry, space radiation effects, and single event upsets); dosimetry-based archaeological and Quaternary dating; dosimetry-based approaches to thermochronometry; accident and retrospective dosimetry (including activation detectors), and dosimetry and measurements related to medical applications.
