Bismuth germanate is a colorless and transparent non-polar oxide crystal with a cubic structure. It is insoluble in water and can emit green fluorescence with a peak of 480nm under the excitation of high-energy particles or high-energy rays (x-rays, γ-rays). BGO crystal has the advantages of strong radiation blocking ability, high scintillation efficiency, excellent energy resolution and non-deliquescent.
