Description

LuAG(Pr) | Scintillation Crystal is a dense, mechanically robust scintillator noted for its fast decay time.

LuAG(Pr) | Scintillation Crystal is an excellent scintillator with high density, fast response time, and high light yield. It is mainly characterized by a high light output of 20 photons/keV, a short decay time constant of 20 ns, and a large effective atomic number of 62.9. LuAG(Pr) with a Pr doping concentration of 3% has slightly higher fluorescence intensity, but the position of the excitation peak does not change for different concentrations.
