Radiation detection material is a central component of nuclear technology finding applications in many critical fields. Developing a highly radiation-sensitive material that shows a facilely detectable response to ultra-low dosage of radiation is a long-term research target and remains to be a challenge. Previously reported most optimal chemical radiation dosimeter can detect low-dosage X- and γ-ray radiations down to 10⁻⁴ Gy. We document here a new photoresponsive coordination polymer showing upgraded radiation detection capabilities with the detection limit on the radiation dose one order of magnitude lower than the previous record. The radiation induced photoluminescence quenching process was elucidated by multiple spectroscopic characterizations.

辐射检测材料是核技术在许多关键领域中发现应用的重要组成部分。开发对辐射非常敏感的材料，该材料对超低剂量的辐射显示出容易检测到的响应，这是一项长期的研究目标，并且仍然是一个挑战。先前报道的最理想的化学辐射剂量计可以检测低至10 ^-4 Gy的低剂量X射线和γ射线辐射。我们在这里记录了一种新型的光响应配位聚合物，该聚合物显示出更高的辐射探测能力，其辐射剂量的探测极限比以前的记录低一个数量级。通过多种光谱表征阐明了辐射诱导的光致发光猝灭过程。
