BGO Crystal
Bismuth germinate Bi4Ge3O12 commonly abbreviated as BGO, is the crystalline form of an inorganic oxide with cubic eulytine structure, colorless, transparent, and insoluble in water. When exposed to radiation of high-energy particles, or other sources, such as gamma rays and x-rays, it emits a green fluorescent light. The light has a peak wavelength of 480nm, with its high stopping power, high scintillation efficiency, good energy resolution, and non-hygroscopes. BGO is a good scintillation material and has found a wide range of applications in high energy physics, nuclear physics, space physics, nuclear medicine, geological prospecting, and other industries.
