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.

Advantage：Unique BaSO4 reflector coating、High precision matching、Quality control of each crystal

Application：Low-cost PET、Small animal PET、Organ-specific PET、Particle detection、Radiation detection

Specification Parameter

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.

Yunjia offers flexible customization of BGO crystals in terms of size, shape, and geometry to meet specific customer requirements. In addition to single crystals, Yunjia also provides tailored scintillator array configurations for various applications.
