Abstract

The invention belongs to the field of high performance scintillant materials and high-energy ray detection and discloses an application of a compound as a scintillant material and a preparation methodthereof. The compound has a chemical general formula AB2X3, wherein A is a monovalent alkali metal cation, B is a monovalent transitional metal cation and X is a monovalent halogen anion. The preparation method comprises the following specific step of preparing the compound with the chemical general formula AB2X3 based on an anti-solvent devitrification method, a cooling devitrification method, afused salt mixing method or a pulling method by taking AX and BX, the molar ratio of which is 1: 2, as raw materials. By regulating components of the compound, a novel scintillant material with the chemical general formula AB2X3 is obtained. The scintillant material has the characteristics of being non-toxic, stable, simple in preparation method and high in photoyield. As the novel scintillant, the material has a huge potential in the field of high energy detection and shows an application prospect of large-scaled industrial production.

Description

technical field [0001] The invention belongs to the field of high-performance scintillator materials and high-energy ray detection, and more specifically relates to the application of a compound as a scintillator material and a preparation method thereof. Background technique [0002] A scintillator is a material that absorbs energy from high-energy particles and releases photons. For solid scintillators, it mainly includes organic scintillators and inorganic scintillators. Compared with organic scintillators, inorganic scintillators have the advantages of high density, large atomic number, and stable physical and chemical properties. They have been widely used in medical imaging, nuclear physics, high-energy physics, and industrial detection, and have become the most important for detecting high-energy rays. one of the parts. [0003] The mainstream scintillator materials currently on the market include CsI / NaI:Tl, PbWO 4 、 Bi 4 Ge 3 o 12 (BGO) etc. However, there i...
