Abstract
Disclosed are a yttrium-doped barium fluoride crystal and a preparation method and the use thereof, wherein the yttrium-doped barium fluoride crystal has a chemical composition of BaYF, in which 0.01≤x≤0.50. The yttrium-doped BaFcrystal of the present invention has improved scintillation performance. The yttrium doping may greatly suppress the slow luminescence component of the BaFcrystal and has an excellent fast/slow scintillation component ratio. The doped crystal is coupled to an optical detector to obtain a scintillation probe which is applicable to the fields of high time resolved measurement radiation such as high-energy physics, nuclear physics, ultrafast imaging and nuclear medicine imaging.
