In this work, a novel method is reported to synthesize ytterbium-doped cesium lead chloride powders, which exhibit a high X-ray scintillation light yield at room temperature. With a simple and inexpensive manufacturing process, this material shows great potential for replacing current commercial scintillators.
Ytterbium-doped cesium lead halides arc 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 (Yb3+:CsPbCl3) 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 Yb3+:CsPbCl3 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 Yb3+:CsPbCl3 for scintillation applications.
