摘要
高能辐射探测和成像技术在高能物理研究、医学成像和工业监测方面有着重要的应用。无铅金属卤化物具有毒性低、稳定性强、光产率高、斯托克斯位移大等特点，在进行高能辐射间接探测方面具有非凡的潜力。本文回顾了用于 X 射线成像的无铅金属卤化物闪烁体材料的最新进展。随后，它列出了闪烁体性能的最重要参数，并介绍了单晶、粉末和纳米晶闪烁体的生产程序。此外，它还讨论了如何制造性能更好的闪烁体薄膜，重点是大面积柔性闪烁体薄膜以及与微结构的耦合。最后，它还讨论了当前使用无铅金属卤化物闪烁体材料增强 X 射线成像所面临的挑战和机遇。
Lead-free metal halide scintillator materials for imaging applications
High-energy radiation detection and imaging technology has significant applications in high-energy physics research, medical imaging, and industrial monitoring. Lead-free metal halides exhibit exceptional potential for conducting indirect detection of high-energy radiation due to their characteristics of low toxicity, strong stability, high light yield, and large Stokes shift. This paper reviews the most recent advances in lead-free metal halide scintillator materials for X-ray imaging. Subsequently, it lists the most important parameters of scintillator performance and introduces the production procedures for single crystal, powder, and nanocrystal scintillators. Furthermore, it discusses the manufacturing of scintillator films with improved performance, focusing on large-area flexible scintillator films and the coupling with microstructures. Finally, it discusses current challenges and opportunities for enhancing X-ray imaging using lead-free metal halide scintillator materials.
