BGO Scintillation Crystal Bismuth Germanate

BGO (Bismuth Germanate) is a high-Z, high-density scintillating crystal. The material has a high atomic number (Z=83 for bismuth) and a density of 7.13 g/cm³, making it a highly efficient gamma-ray absorber.
Due to the high-Z properties of the material, the gamma-ray-induced light absorption fraction is significantly enhanced, resulting in an excellent peak-to-total ratio.

BGO (Bismuth Germanate, Bi₄Ge₃O₁₂) is a high-density, high-Z inorganic scintillator crystal renowned for its excellent gamma-ray stopping power, good energy resolution, and strong radiation resistance. The BGO crystal is widely used in applications such as positron emission tomography (PET), high-energy physics experiments, and industrial gamma-ray detection.

 

EBO offers flexible customization of BGO crystals in terms of size, shape, and geometry to meet specific customer requirements. In addition to single crystals, EBO also provides tailored scintillator array configurations for various applications. EBO's manufacturing capabilities support array pixel sizes as small as 0.2 × 0.2 mm, enabling high-resolution imaging.

 

Common internal reflective materials include BaSO₄, ESR, and E20 reflective film. These can be selected or recommended based on the application environment to optimize light collection efficiency and overall system performance.
