BGO crystal

Bismuth germanate(Bi4Ge3O12) commonly abbreviated as BGO, is the crystalline form of an inorganic oxide with cubic eulytine structure, colorless, transparent and insoluble in water. BGO crystal has an extremely high density and Z valule, which make tis crystal very suitable for detection of natural radioactivity(U, Th, K), for high energy physics application(high photofraction) or in compact compton suppression spectrometers



When exposed to the irradiation of high energy particles or other sources, such as gamma-rays, X-rays, it emits a green fluorescent light with a peak wavelength of 480nm. With its high stopping power, high scintillation efficiency, good energy resolution and non-hygroscopic, BGO is a good scintillation material and has been found a wide range of applications in high energy physics, nuclear physics, geological exploration and other industries



EPIC has developed an unique technology for BGO crystal growing and scaled up into quantity production in the R&D center of its insititude, please contact us for further details
