Scintillators

Scintillating crystal -EBO

Scintillation crystals are commonly utilized in detectors to transform X-rays or gamma rays into light pulses, which are subsequently detected by either a Photomultiplier Tube (PMT) or a Silicon Photomultiplier (SiPM).

EBO scintillation crystal manufactures a wide variety of scintillation crystals, such as BGO, LYSO,CsI, GAGG, NaI etc., meticulously chosen for their high density, exceptional brightness, outstanding light output, and rapid decay times. These crystals are extensively applied in X-ray and gamma-ray detection, non-destructive testing, medical imaging, and scientific research.

How to choose the right scintillation crystal for different application fields?

Nuclear medicine imaging

Such as PET and SPECT, scintillation crystals are required to have high light output to improve detection sensitivity, fast decay time to achieve fast imaging and high temporal resolution, and good matching of emission spectrum with photodetectors to improve light collection efficiency. LYSO and BGO are commonly used in PET, while NaI (Tl) is widely used in SPECT.

High-energy physics experiments

High-energy particles are usually required to be detected. Scintillation crystals should have high density and high atomic number to effectively block and detect particles, and have good energy resolution to distinguish particles of different energies. For example, BGO crystals are suitable for such scenarios.

Security inspection equipment

Such as luggage security at airports and customs, which requires rapid and accurate detection of radioactive substances or prohibited items. At this time, scintillation crystals should have high light output and fast response speed to quickly generate signals and analyze them. NaI (Tl) crystals can meet some of these requirements.

Industrial non-destructive testing

Mainly detects defects inside industrial parts, requiring scintillation crystals to have high detection efficiency and good spatial resolution for X-rays or γ-rays. CsI (Tl) is often used in industrial flaw detection due to its good response to rays and relatively high resolution.

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.

LYSO Scintillation Crystal Cerium doped Lutetium

LYSO(Ce) - Lutetium Yttrium Orthosilicate (Lu₂SiO₅:Ce) is a relatively new scintillator crystal that features high density, high light output, short decay time and good radiation resistance. These properties make it ideal for detecting and measuring ionizing radiation such as gamma rays and positrons.

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.
