Problems solved by technology

Most halide scintillators often need to be tightly packaged before use, which has a great impact on the cost of material storage and application
At present, the non-(or weak) deliquescent halide scintillators that are widely used are mainly thallium-doped cesium iodide (CsI:Tl + ), this material has a high light output comparable to NaI:Tl and is c

Abstract

The invention provides an exciton light-emitting halide scintillator, a thin film, a single crystal, a preparation method and application. The exciton light-emitting halide scintillator has the following chemical formula: (A1-xAx') 5 (B1-yB'y) 3 (X1-zX'z) 8, wherein A and A'are respectively selected from one of Li, Na, K, Rb, Cs, In and Tl, and x is more than 0 and less than or equal to 1; B and B'are respectively selected from one of Cu, Ag and Au, and y is more than 0 and less than or equal to 1; and X and X' are respectively selected from one of F, Cl, Br and I, X and X 'are not the same element, and z is more than 0 and less than 1. The exciton light-emitting halide scintillator has the advantages of no deliquescence, high fluorescence quantum efficiency, high light output, low afterglow and the like, can be used for detecting X rays, gamma rays and neutrons, and has important application prospects in the fields of nuclear medicine imaging, security check, petroleum exploration wells, industrial detection and the like.

Description

technical field [0001] The invention relates to the field of ceramic materials and preparation, in particular, the invention relates to a novel exciton luminescent halide scintillator, thin film, single crystal, preparation method and application. Background technique [0002] A scintillator is a material that can convert high-energy rays or particles into visible light or ultraviolet light, and has a wide range of applications in the field of radiation detection. With the continuous improvement of the performance requirements of radiation detection materials in the fields of homeland security, nuclear medical imaging, and high-energy physics, it is urgent to develop new high-performance scintillators. [0003] Thallium-doped sodium iodide (NaI:Tl + ) mainly, this material has the advantages of high light output (~40000photons / MeV) and low cost, but it deliquesces in the air and needs to be packaged before use. New scintillators developed in recent years, such as cerium-do...
