Product Description

LuAG:Pr, or lutetium aluminum garnet doped with praseodymium, is another synthetic crystalline material with a cubic structure. It is also commonly used as a scintillation detector in various scientific applications, especially thermal neutron detection.  LuAG:Pr has a high thermal neutron capture cross section, meaning it can efficiently convert thermal neutron radiation into light, making it a popular choice for thermal neutron detection in nuclear reactors and other nuclear energy-related applications.  LuAG:Pr also has favorable scintillation properties with high light output and fast response time, making it useful in medical imaging, high-energy physics, and other fields that require precise and sensitive detection of radiation. Overall, LuAG:Pr is a multifunctional scintillation material with many applications in radiation detection and is a promising material for future research in this field.

LuAG:Pr scintillator crystals have the following issues which should be noted. They have a light emission which a is good part is above 500nm, a region where photomultipliers are less sensitive and It`s intrinsically radioactive making it unacceptable for some applications. They are susceptible to radiation damage, starting with doses between 1 and 10 Gray (10² - 10³ rad). Reversible with time or annealing.
