Recently, low-cost perovskite single crystals have attracted intensive attention due to their excellent optoelectronic properties and improved stability when compared to polycrystalline films for various applications, such as solar cells (Kojima et al., 2009; Lee et al., 2012; Tsai et al., 2016; Sahli et al., 2018), lasers (Gu et al., 2016; Veldhuis et al., 2016), radiation detection (Kim et al., 2017), and so on. The unique optoelectronic properties and low-cost growing processes for large-sized single crystals also make them greatly suitable for radiation detection. In this review, we summarize various synthesis methods of perovskite single crystals and introduced the high radiation detection performance of the perovskite single crystal. The advantages and limitations of halide perovskite single crystals as radiation detector candidates will be discussed in detail, and corresponding future development trends can be expected by overcoming current obstacles (Leijtens et al., 2018; Boyd et al., 2019), such as ion migration (Eames et al., 2015), stability, etc.
最近，低成本的钙钛矿单晶因其优异的光电性能以及与用于各种应用（如太阳能电池（小岛等人，2009年；李等人，2012年；蔡等人，2016年；萨利等人，2018年）、激光器（顾等人，2016年；韦尔杜伊斯等人，2016年）、辐射探测（金等人，2017年）等）的多晶薄膜相比有所提高的稳定性而备受关注。大尺寸单晶独特的光电性能和低成本的生长工艺也使其非常适合用于辐射探测。在这篇综述中，我们总结了钙钛矿单晶的各种合成方法，并介绍了钙钛矿单晶的高辐射探测性能。卤化物钙钛矿单晶作为辐射探测器候选材料的优点和局限性将被详细讨论，并且通过克服当前的障碍（莱延斯等人，2018年；博伊德等人，2019年），如离子迁移（伊姆斯等人，2015年）、稳定性等，可以预期相应的未来发展趋势。
