https://www.scintillator-crylink.com/scintillator-products/tlcsi/

https://www.scintillator-crylink.com/scintillator-products/tlcsi/Pure CsI is also known as a scintillator but exhibits rather different properties. It exhibits fast (~10 ns) emission, peaking at 310 nm, but its scintillation yield at room temperature is very low. But its light yield at 77 K reaches an impressive 100,000 ph/MeV, that makes pure CsI a very attractive scintillator for detector applications at low temperatures.TI:CsI is one of the brightest scintillators. It has most of its emission in the long wavelength part of the spectrum (>500nm), it is well-suited for photodiode readout. TI:CsI crystal has high light yield, no cleavage surface, low melting point and easy growth. It has good optical properties, mechanical properties, physical and chemical stability and high photoelectric conversion efficiency. It has been widely used in many fields, such as Security check, Detection of neutrinos, Detection of neutrinos and γ-ray, XCT. Na-doped cesium iodide (Na:CsI) is an important alkali metal halide inorganic scintillator that is widely used as laser-stimulable transparent film and X-ray detection materials. Na:CsI has peaking emission at 420 nm, and its decay time is about 630 ns, which has relatively high luminescence intensity and effective atomic number compared to organic scintillator. Recently, it is found that Na:CsI is a promising suitable detection material for dark matter scientific exploration.

FEATURES Matched with silicon photodiodes High light yield Low melting point Easy growth Good optical and mechanical properties Good physical and chemical stability High photoelectric conversion efficiency

APPLICATIONS Security check Detection of neutrinos Detection of neutrinos γ-ray XCT PET Position sensitive detector Geological exploration Industrial CT camera
