However, the short range of electrons emitted by these gases makes detection challenging. Current methods, such as ionization chambers and liquid scintillation, do not offer at the same time good sensitivity, real-time analysis and ease of implementation. We demonstrate an approach using a gas–solid mixture to overcome these limitations. We synthetized a transparent and scintillating nanoporous material, an aerogel of Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>:Ce<sup>4+</sup>, and achieved real-time detection with an efficiency of 96% for <sup>85</sup>Kr and 18% for <sup>3</sup>H. The method reaches a sensitivity below 100 mBq per cm<sup>3</sup> over 100 s measurement time. We are able to measure simultaneously as mixtures containing both <sup>3</sup>H and <sup>85</sup>Kr a capability not possible previously. Our results demonstrate a compact and robust detection system for inline measurement of strategic radioactive gases. This combination of concept and method enhances nuclear power plant management and contributes to environmental safeguarding. Beyond the detection issues, this concept opens a wide field of new methods for radionuclide metrology.</p>","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":null,"pages":null},"PeriodicalIF":35.0,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142118091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is still a challenge to achieve high sensitivity, low dark current and low detection limit in a single material. The deep reason for this is the trade-off between the material’s μτ product and resistivity. Here we report the construction of an organic–inorganic hybrid anti-perovskite ((2-Habch)3Cl(PtI6)) with indirect transition and low orbital symmetry at the band edge to achieve an ultralong intrinsic lifetime and thus break the trade-off. (2-Habch)3Cl(PtI6) achieves an unprecedented long carrier lifetime of >3 ms, leading to a large μτ product of 6.25 × 10−3 cm2 V−1 and high resistivity of 1012 Ω cm, outperforming most X-ray detection materials. These properties enabled the development of X-ray detectors that simultaneously achieve an ultralow dark current of 0.21 nA cm−2, high sensitivity of 1.0 × 104 µC Gyair−1 cm−2, ultralow detection limit of 2.4 nGyair s−1 and excellent operational stability with no observable baseline drift, outperforming state-of-the-art perovskite single-crystal detectors. The rare combination of high performance in almost every figure of merit in the anti-perovskite-based X-ray detector could enable new-generation X-ray detection systems. The researchers synthesize organic–inorganic hybrid inverse perovskites that exhibit excellent carrier lifetime and mobility–lifetime product and high resistivity, enabling stable X-ray detectors with performance arguably outperforming state-of-the-art perovskite single-crystal detectors.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":null,"pages":null},"PeriodicalIF":32.3,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142042674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
