Cerium doped Lutetium Aluminum Garnet or LuAG(Ce) is a relatively dense and fast scintillation material, its density of 6.73 g/cm3 is about 94% of the density of BGO (7.13 g/cm3). and its decay time is much faster (70 ns) than that of BGO (300 ns), these good properties makes it fit for time dependent and coincidence scintillating detection. The wavelength of scintillation emission for LuAG(Ce) is about 535 nm, which is ideal for Photo Diode (PD) and avalanche diode readout. The LuAG(Ce) crystal material is mechanically and chemically stable, and can be machined into a variety of shapes and sizes including prisms, spheres and very thin plates. Like the Ce:YAG crystals, Ce:LuAG could be used for imaging screens, comparing to Ce:YAG, Ce:LuAG has higher density which makes its screens thinner and higher in spatial resolution.
Hangzhou Shalom EO offers LuAGCe) scintillation crystals and LuAG(Ce) thin screens, they are widely used in Position Emission Tomography (PET) Scanners, high energy gamma and charged particle detection, and high spatial resolution imaging screens for gamma, X, beta and UV rays detection.
