BGO
BGO
Bismuth Germanium Oxide (also known as Bismuth Germanate) is an inorganic chemical compound with the chemical formula Bi4Ge3O12 (BGO). It is the most common oxide-based scintillator compound for detector applications. Vital Materials also produces Czochralski-grown crystals.
BGO is a colorless, transparent, non-deliquescent inorganic scintillator crystal. It is characterized with strong ability to block high-energy rays, and has high resolution. It is widely applied in the research fields of elementary particles, space physics, and high-energy physics.
