Rare-earth-mixed barium borophosphate flashing luminous material, its preparing method and use

Abstract

This invention relates to a light emitting material with strong light output and quick attenuation excited by X rays and its preparation method, in which, the composition formula of the flash luminous material is (Ba(1-x)Eux)3BP3012, in which, x is the content(0<x<0.10) of an activation agent and the material is prepared by a traditional solid composition method, when 0<x<0.01, Eu3+ can be recovered to Eu2+ in air, but when 0.01< or equal to x<0.10, a double pot recovery method is needed for high temperature burning.

Description

Rare earth-doped barium borophosphate scintillation material and its preparation method and application technical field The present invention relates to a scintillating luminescent material and its preparation method and application, more precisely, it relates to rare earth-doped barium borophosphate scintillating luminescent material with strong light output and fast decay under X-ray excitation, its preparation method and application . Background technique Inorganic scintillation materials are a class of luminescent materials with high value and great economic benefits. Due to the development of high technologies such as nuclear physics, magnetic resonance imaging, positron emission tomography (PET), X-ray computerized tomography (ie CT) and Requirements, new inorganic scintillation materials made significant progress in the late 1980s, opened up another new application market, and it is expected that it will have greater development in the 21st century. In recent years...

AI Technical Summary

Problems solved by technology

The currently used scintillation materials are mainly NaI:Tl, PbWO4, Bi4Ge3O12, etc., but they still have some disadvantages, such as NaI:Tl is easy to deliquescence, long afterglow, Bi4Ge3O12 has long afterglow, and PbWO4 has low luminous efficiency. More importantly, these The materials have been covered by foreign patents, which sets up trade barriers for such materials produced in my country to enter the European and American markets

So far, there have been no reports on the successful preparation of novel X-ray-excited high-efficiency scintillation materials using a safer and simpler method.
