BGO (Bismuth Germanate, Bi₄Ge₃O₁₂) is a high-density inorganic scintillator widely used for gamma-ray and radiation detection. Its strong stopping power and low afterglow make it suitable for medical imaging and nuclear applications. What are the main advantages of BGO? BGO offers very high density, excellent gamma-ray absorption efficiency, good energy resolution, low afterglow, and stable light output under long-term operation. How does BGO compare to NaI(Tl) or CsI(Tl)? Compared with NaI(Tl) and CsI(Tl), BGO has much higher density and stopping power but lower light yield. It is preferred when detection efficiency and compact detector size are more important than maximum light output. What is the decay time and emission wavelength of BGO? BGO has a typical decay time of ~300 ns and emits light with a peak around 480 nm, compatible with PMTs and silicon-based photodetectors. Is BGO hygroscopic? No. BGO is non-hygroscopic, making it easier to handle and integrate compared with NaI-based scintillators. What applications commonly use BGO crystals? PET and CT imaging, nuclear spectroscopy, high-energy physics detectors, industrial radiation monitoring, and space or defense-related radiation systems. Do you offer custom sizes and surface finishes? Yes. BGO crystals can be supplied as blocks, plates, pixels, or custom geometries, with optical polishing and surface treatments to match your detector design. Are your BGO crystals suitable for research and OEM use? Absolutely. Our BGO scintillators are supplied to universities, research institutes, and OEM manufacturers with consistent quality and long-term reliability.
