BGO (Bismuth germanate) – Electro-optic Crystal – Customized Products

BGO crystal, also known as bismuth germanate crystal, with the chemical formula Bi4Ge3O12, 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 it is exposed to radiation from high-energy particles or gamma rays or X-rays. with higher stopping power, efficient scintillation, first-class energy resolution, and non-hygroscopicity, BGO is an excellent scintillation material, ideal for a wide range of applications in
high-energy physics, nuclear physics, space physics, nuclear medicine, geology, etc. BGO crystals have low dark With the advantages of low electrical conductivity, colorless transparency, and insolubility in water, BGO can also be used in nonlinear optics, such as Pukels boxes, and photorefractive devices in the ultraviolet range by its high electro-optical coefficient. 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.
