Bismuth germanate (Bi4Ge3O12 )

Bismuth germanate (Bi4Ge3O12 ) crystal is an inorganic oxide with cubic eulytine structure, colorless, transparent and insoluble in water. It posses a high stopping power, high photopeak efficiency, non-hydroscopic, low afterglow and easy to be fabricated. therefore it is a good scintillation material and has found a wide applications in high energy physics, nuclear physics, space physics, nuclea medicine, geological prospecting and other industries.
