EBO offers premium CdWO4 Scintillation Crystal for high-precision radiation detection and imaging applications. Known for its high density, excellent X-ray absorption, and low afterglow, CdWO4 Scintillation Crystal is widely used in medical imaging, industrial CT, and high-energy physics experiments. As a leading Scintillation Crystal manufacturer, EBO ensures stable quality and reliable performance for both research and industrial use.
CdWO4 (Cadmium Tungstate) is a high-density scintillator with a high Z and relatively high light yield. CdWO4 scintillator's strong light output and extremely low afterglow make it an ideal choice for CT detectors in both medical and industrial applications, particularly when paired with silicon photodiodes. The material also exhibits excellent radiation resistance and minimal temperature dependence across the 0°C to 60°C range. CdWO4 scintillator's high density makes it particularly suitable for security scanning systems used in baggage, container, and vehicle inspections.
EBO offers CdWO4 crystals in a wide range of customized shapes and sizes to meet specific application needs. In addition to single-crystal, EBO can fabricate linear arrays and two-dimensional array configurations. These arrays typically use TiO₂ as the internal reflector material between pixels to enhance optical performance.
At EBO, we specialize in Scintillation Crystal research, production, and customization. Our CdWO4 Scintillation Crystal products undergo strict quality control to ensure uniform optical properties and stable performance. We offer:
Customized crystal sizes and shapes.
Competitive pricing for bulk orders.
Technical support for integration into your system.

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.

Cesium iodide (CsI(Tl)), activated by thallium, is one of the most efficient scintillators discovered so far. CSI Crystal exhibits thallium-activated luminescence with an emission peak at 550 nm and a light output of 45% relative to NaI(Tl). In contrast, cesium iodide activated by sodium (CsI(Na)) features a sodium-activated emission peak at 420 nm and a higher light output (85% of NaI(Tl)). Both materials share properties such as deliquescence, soft and plastic mechanical behavior, radiation resistance, high-temperature tolerance, and fast timing characteristics (for pure CsI). They are widely used in particle detection for high-energy physics experiments, medical SPECT imaging, baggage/container security inspection, industrial level sensing and non-destructive testing, and cosmic ray research in space physics.
