Bismuth Germanate (BGO) Scintillation Crystal Description
Bismuth Germanate (BGO) Scintillation Crystal is a cubic structure with 7.13g/cm^3 density. Because of its high density and atomic number of bismuth (83), BGO is a high Z and density scintillation material. It is a highly effective gamma-ray absorber. BGO Scintillation Crystal has an emission peak of 480 nm which couples well with PMT and SiPM. Unlike other Scintillation crystals, BGO shows an unparalleled absorption rate at photopeak. Bismuth Germanate (BGO) Scintillation Crystal has Mechanically robust characteristics and is non-hygroscopic. Also, it has no cleavage planes, people can machine BGO into different shapes and geometries.
