Description

Eu:SrI2 Scintillator Crystal —A scintillation with highlight output and  excellent energy resolution 

Efficient radiation detectors must be able to distinguish between different radioactive sources and for gamma-ray detection, scintillator materials with high energy resolution, high light yield, and a short decay time are required. Compared to traditional scintillation crystal materials, Eu:SrI₂ crystal has a higher light yield and better energy resolution. In addition, Eu:SrI₂ crystal has lower hygroscopicity and can be stored in an environment with low water content with stable characteristics indefinitely. The emission wavelength of Eu:SrI₂ crystal is between 400-500 nm, which matches well with the mainstream PMT spectral sensitive region that is beneficial for the detection of scintillation photons. At the same time, Eu:SrI₂ crystal is not sensitive to changes in ambient temperature which will make its application scene more extensive, such as Gamma ray spectroscopy, elemental isotope screening and scintillation detectors for safety inspection equipment, in industrial and medical CT, ultra-high resolution X-ray imaging, etc.f

With the application of nuclear safety inspection technology in anti-terrorism and the continuous development of nuclear medical imaging, the requirements for light output and energy resolution of scintillation crystals are continuously improved. Security applications and nuclear non-proliferation depend on the rapid identification of highly enriched uranium, radioactive sources and other special nuclear materials. Halide crystals have been widely used as high-energy physics, nuclear medicine, safety inspection and address exploration as radiation materials since their invention in 1948. Eu:SrI₂ is expected to become a new generation of gamma scintillator due to its high light output, good energy resolution and high effective atomic number. We specialize in providing high quality crystals to our customers based on their requirements.
