Product Description


TI:CsI, Na:CsI,CsI Scintillator Crystals
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 is a scintillator with excellent comprehensive performance. It has been widely used in many fields, such as Security check, Detection of neutrinos, Detection of neutrinos andγ-ray, XCT.

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.

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.As an inorganic scintillator, Na:CsI 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.
