Abstract

The invention relates to a quick-attenuation high-light-output gallium oxide scintillation crystal and a preparation method thereof. The chemical formula of the gallium oxide scintillation crystal isbeta-Ga2O3: M, and M is one or two of doped Ge4<+> or Al3<+> ions. Compared with the prior art, the beta-Ga2O3: M gallium oxide scintillation crystal provided by the invention has the advantages thatthe attenuation time is shorter, meanwhile, the light output is not weakened, and the comprehensive scintillation performance of the crystal is improved.

Description

technical field

[0001] The invention belongs to the technical field of preparation of nuclear radiation detection materials, and relates to a gallium oxide scintillation crystal with fast decay and high light output and a preparation method thereof. Background technique

[0002] Detection and imaging technologies centered on scintillation crystals have been widely used in nuclear medicine, high-energy physics, safety inspection, industrial non-destructive testing, space physics, and nuclear prospecting. The requirements for fast-decay scintillation crystals are getting higher and higher. The scintillator is the core component of the scintillation detection system, and the performance of the scintillator directly affects and restricts the performance of the scintillation detection system. In high count rate occasions, TOF-PET and other fields require scintillators to have as fast a decay time as possible; the high light output of scintillators is conducive to the system to a...
