Pr:LuAG Scintillation Crystals

FEATURES

DESCRIPTION In application of medical imaging, Pr doped Lu3Al5O12(LuAG), which was first introduced in 2005, has attracted great attention for its good scintillator performance having high density (6.7 g/cm3), fast decay time(~20 ns), high light yield (~0,000 ph/MeV) and excellent energy resolution of 4.6%. Those demonstrated it a competitive scintillator.Scintillators with high light yield and fast decay are essential in the time-of-flight (TOF) technique for a satisfactory coincidence timing resolution to give precise TOF information. Among garnets, Pr:Lu3Al5O12 was pointed out as a promising fast scintillator already in 2005. Pr:LuAG has a decay time of about 20 ns, which is even shorter than that of Ce:LSO. The light yield of Pr:LuAG is 3 times higher than that of BGO. In addition, Pr:LuAG has a high density of 6.7 g/cm3 which is important of x and g-ray detection, as well as an outstanding energy resolution of 4.6% at 662 keV that is beneficial for gamma ray discrimination. It has been attracting much attention and is presently commercially used in Positron Emission Mammography (PEM).
