BGO crystal is also known as bismuth germanate crystal, with the chemical formula Bi4Ge3O12. It is a crystalline form of an anode oxide. 

BGO crystal has a cubic structure, is colorless and transparent, and is insoluble in water. It emits green fluorescence with a peak wavelength of 480 nm when exposed to radiation from high-energy particles, gamma rays, or X-rays. 

With higher stopping power, efficient scintillation, first-class energy resolution, and non-hygroscopicity, BGO is an excellent scintillation material. It is ideal for many applications in high-energy physics, nuclear physics, space physics, nuclear medicine, geology, etc. 

BGO crystal hase low dark with the advantages of low electrical conductivity, colorless transparency, and insolubility in water. By its high electro-optical coefficient, BGO can also be used in nonlinear optics, such as Pukels boxes, and photorefractive devices in the ultraviolet range. 

BGO is also widely used as a scintillator crystal, which produces photons in the visible region when the crystal is subjected to high-energy gamma rays.

Features of BGO Crystal:

  • High electro-optical coefficient
  • Low dark conductivity
  • Large size components or wafers up to 3″
  • Customized upon request
