Ytterbium-doped cesium lead halides are quantum cutting materials with exceptionally high photoluminescence quantum yields, making them promising materials as scintillators. In this work, we report ytterbium-doped cesium lead chloride (Yb:CsPbCl) with an X-ray scintillation light yield of 102,000 photons/MeV at room temperature, which is brighter than the current state-of-the-art commercial scintillators. The high light yield was achieved based on a novel method of synthesizing Yb:CsPbCl powders using water and low-temperature processing. The combination of high light yield and the simple and inexpensive manufacturing method reported in this work demonstrates the great potential of Yb:CsPbCl for scintillation applications.
镱掺杂的铯铅卤化物是具有极高光致发光量子产率的量子切割材料，使其成为很有前景的闪烁体材料。在这项工作中，我们报道了室温下X射线闪烁光产率为102,000光子/兆电子伏的镱掺杂氯化铯铅（Yb:CsPbCl），其比目前最先进的商用闪烁体更亮。基于一种使用水和低温工艺合成Yb:CsPbCl粉末的新方法实现了高光产率。这项工作中报道的高光产率与简单且低成本的制造方法相结合，证明了Yb:CsPbCl在闪烁应用方面的巨大潜力。
