Scintillation Crystals
GOS ceramic (Gd2O2S) belongs to hexagonal system structure, with no harmful to environment, high chemical stability and machinability. GOS doped with rare earth ion has relatively high light output and extremely low afterglow, saying <0.1% @3ms.
The GOS scintillation screen, based on unique phosphor manufacturing and processing technology, delivers exceptional performance and can efficiently match various photoelectric converters such TFT, CCD and PD, enabling precise digital conversion of detected pbject pixels.
Bi4Ge3O12 refers to a scintillation crystal made from Bismuth Oxide and Germanium Oxide. BGO is a widely used inorganic scintillator material known for its several desirable characteristics in radiation detection and medical imaging applications, such as high density, high effective atomic number, and high stopping power for gamma rays.
YAG (Ce) is a non-hygroscopic, chemically inert inorganic scintillator, the wavelength of maximum emission at 550 nm is well matched to CCD sensitivity, and it is reasonably fast (75 ns decay time) with a relatively high light yield of 12% of NaI(TI) scintillator.
YAP (Ce) scintillator crystal has fast decay time(28 ns) abd relatively high light yield(40% of NaI:TI), the emission peak is 360-380 nm, which can be effectively matched with most of the current read out system. YAP(ce) can be machining precisely, used for gamma and x-ray counting, electron microscopy, electron and X-ray imaging screens.
Cerium doped silicate yttrium, YSO(Ce), belongs to monoclinic rare earth ortho-silicate crystal, it is similar with the LYSO(ce) crystal, while generally used as a semiconductor and in photo optic applications. YSO(ce) crystal shares the same emission peak 420 nm with LYSO(ce),
LuAG(Ce) is a typical scintillation crystal with garnet structure, the light yield is 25,000 photons/Mev, it also has many other excellent properties, such as high density, large Zeff and good mechanical property.
Lead tungstate (PbWO4) is one of the most dense oxide crystal (8.3 g/cm3), it is distinguished by its short radiation length (0.9 cm), small Moliere radius (2.19 cm) and strong irradiation hardness.
