Abstract

The invention belongs to the technical field of scintillator materials, and discloses a chloride crystal and glass composite transparent optical function material and a preparation method and application thereof. The transparent optical function material comprises the following components: 50-99 mol% of a chloride crystal phase and 1-50 mol% of a glass phase. The chloride crystal phase is a crystal phase formed by more than one of alkali metal chloride or alkaline earth metal chloride. The glass phase is formed by boron oxide or phosphorus pentoxide. The alkaline earth metal chloride is more than one of CaCl2 and SrCl2. The alkali metal chloride is more than one of LiCl, NaCl, KCl, RbCl and CsCl. The invention also discloses a preparation method of the material. The material provided by the invention has the advantages of high transparency, high crystal content, continuously adjustable crystal content, strong water erosion resistance, and good luminescence property because of doping of luminescent ions. The material provided by the invention is used for preparing a scintillator material and / or a laser material.

Description

technical field [0001] The invention relates to a transparent composite optical functional material, in particular to a transparent composite material containing chloride crystals and glass, a preparation method and application thereof. Background technique [0002] Composite materials are widely used materials, and transparent composite materials have important applications in high-energy ray detection, laser, infrared luminescence and other fields. In the field of high-energy ray detection, scintillator material is a material that can effectively convert various invisible high-energy rays (such as X-rays, α-rays, β-rays, γ-rays, and high-energy particles such as protons and neutrons) into visible light or ultraviolet light. A luminescent material widely used in high-energy physics, medical imaging, astrophysics, atomic energy, and homeland security. [0003] At present, composite materials play a very important role in scintillators, such as 6 LiF and ZnS: Ag scintillati...
