The invention relates to a preparation method of a lead-free
halogen micron
crystal as well as a product and application of the lead-free
halogen micron
crystal, and belongs to the technical field of preparation of the lead-free
halogen micron
crystal. The invention discloses a preparation method of a lead-free halogen micron crystal, which comprises the following steps: dissolving
silver chloride (AgCl) and
rubidium chloride (RbCl) in
dimethyl sulfoxide, and extracting by an anti-
solvent method to obtain the Rb2AgCl3 lead-free halogen micron crystal. The Rb2AgCl3 lead-free halogen microcrystal is prepared by using a normal temperature method and has the advantages of simple experimental steps and easiness in operation, compared with lead-containing
halide, the prepared Rb2AgCl3 lead-free halogen microcrystal solves the problem of
toxicity of lead, and particularly compared with cesium-lead-
bromine, the luminous quantity of the Rb2AgCl3 lead-free halogen microcrystal prepared by the method is higher than that of cesium-lead-
bromine under X rays when the Rb2AgCl3 lead-free halogen microcrystal is used as a
scintillator material, and the service life of the Rb2AgCl3 lead-free halogen microcrystal is prolonged. And the process for preparing the micron crystal
powder into the film is simple, and after the film is prepared, materials in the film are uniformly distributed, so that the imaging effect is better.
