Bismuth Germanium Oxide (Bi4Ge3O12)-Powder

Characteristic

Bismuth Germanate or Bismuth Germanium Oxide (BGO) is the general name of Bi₂O₃-GeO₂ series compounds. The chemical formulas of the two most common Bismuth Germanate compounds are Bi₄Ge₃O₁₂ (CAS: 12233-56-6) and Bi₁₂GeO₂₀ (CAS: 12233-73-7).

Bismuth germanate or "BGO" is usually used to specifically refer to Bi₄Ge₃O₁₂, which is a colorless transparent crystal of cubic crystal system. Under the action of high-energy particles or high-energy rays (beta rays and x-rays), it can emit green fluorescence with a peak wavelength of 480 nm, and can detect high-energy particles and high-energy rays with its scintillation performance.
