Bismuth germanate (BGO)

Bismuth Germanate (BGO) is a colorless and transparent non-polar oxide crystal with a cubic structure. Insoluble in water, in high-energy particles or high-energy rays (X-rays γ Under the excitation of X-rays, a green fluorescence peak of 480nm can be emitted BGO is widely used in the fields of ray detection and medical imaging, which can convert high-energy radiation, such as gamma rays and X-rays, into visible light

BGO has high density and effective Atomic number, which makes it have excellent absorption capacity for high-energy radiation. This feature is very valuable in ray detectors and can improve detection efficiency The scintillation light of

BGO is blue, matching with the spectral response of many Photomultiplier tube, which is conducive to achieving high detection efficiency. In addition, BGO has a long attenuation time, which is an important advantage for some applications such as Positron emission tomography (PET) imaging Finally, BGO has good chemical stability and can maintain its performance in various environments The above performance characteristics make BGO an important material in the field of scintillation crystals
