Pr:LuAG
Pr: LuAG crystal (chemical Pr: Lu3Al5O12, also known as Pr-doped aluminium garnet crystal) is a scintillation crystal with excellent performance and is widely used in high energy physics, oil logging, and other fields. The light output is up to 20,000 photons/MeV, which is about three times that of BGO. Decay time (about 20ns) and energy resolution (4.9%@662KeV) are better than BGO and Ce: LYSO. Pr: LuAG crystals have a strong ability to prevent gamma rays, and are non-tidal, inexpensive. Therefore, Pr: LuAG crystals have important applications in nuclear medicine imaging and other fields. In particular, Pr: LuAG crystals have a decay time of 20ns and are well suited for applications such as time-of-flight positron emission tomography (TOF-PET) and fast ion imaging. The Pr: LuAG crystal is also suitable for positron emission breast cancer scanners (PEM).
