摘要: X射线诱导光致变色材料(X-ray induced photochromic materials, XP材料)因具有辐射剂量依赖的变色性质,在国防安全、核能开发利用、工业探伤和医学成像等领域具有广泛的应用前景。近年来,国内外科学家已发展了多种XP材料,深入探讨了其辐射变色机制,并作了特异性应用研究,亟需综合论述其变色机理和应用领域。本文综述了X射线辐射变色性质的材料体系,并根据其化学组成和变色特点进行了归纳,对比各种类型XP材料的优缺点,讨论了X射线诱导光致变色的机理,如色心形成和氧化还原反应等过程。最后,介绍了其在X射线探测器以及医学和工业中的潜在应用,并展望了其未来的发展方向。本文对发展性质更优异、场景适用性更灵活的XP材料后续研究具有重要意义,可促进X射线诱导光致变色材料的商业化应用进程。

Abstract: X-ray induced photochromic materials (XP materials), characterized by their radiation dose-dependent coloration properties, exhibit broad application prospects in fields such as national defense and security, nuclear energy development and utilization, industrial nondestructive testing, and medical imaging. In recent years, scientists worldwide have developed diverse XP material systems, conducted in-depth investigations into their radiation-induced coloration mechanisms, and explored their specialized applications, highlighting the urgent need for a comprehensive review of their working principles and application domains. This article systematically summarizes the material systems exhibiting X-ray-induced photochromic behavior, categorizing them based on chemical composition and coloration characteristics. The advantages and limitations of various XP materials are comparatively analyzed, while the underlying mechanisms of X-ray-induced photochromism—such as color center formation and redox processes—are discussed. Furthermore, their potential applications in X-ray detection, medical diagnostics, and industrial monitoring are introduced. Finally, future research directions are proposed to advance the development of XP materials with enhanced performance and broader scenario adaptability. This review holds significant implications for guiding subsequent research on optimizing XP materials and accelerating their commercialization process, thereby facilitating the practical implementation of X-ray-induced photochromic technologies.
