This invention belongs to the field of
radiation detection and discloses a rare-earth-doped
phosphate microcrystalline glass for high-energy
radiation detection, its preparation method, and its application. The rare-earth-doped
phosphate microcrystalline glass comprises 0.01~2 mol% rare-earth ions, wherein the rare-earth ions are Eu. 2+ The crystalline phase precipitated in the glass-
ceramic is LiSrPO4. The preparation method includes the following steps: weighing the raw materials by
molar percentage, thoroughly
grinding them, melting them to obtain a glass melt, cooling and shaping them into a transparent glass block, annealing to obtain a precursor glass, and then heating, holding, and cooling to obtain the glass-
ceramic. The preparation method of this invention is simple, can prepare large-size samples, is low-cost, and is easy to
mass-produce industrially. The obtained rare-earth-doped
phosphate glass-
ceramic possesses excellent optical properties and high-energy
ray and high-
energy particle detection performance, superior to commercially available
lithium-
ion scintillator glass. It can be used in
radiation detection, energy exploration,
environmental monitoring, and other related fields, and has broad application prospects.
