LuAP(Ce) Scintillation Crystals
Lutetium Aluminium Perovskite (LuAP(Ce) - LuAlO3:Ce) scintillator crystals are relatively dense (8.34g/cm³), have a high Z (64.9) and have a a fast decay time (18ns). With a peak emission of 365nm, LuAP(Ce) output is well is well matched to photodiodes avalanche photodiodes APDs and silicon photomultipliers (SiPMs). In addition these crystals have good temperature properties.


LuAP(Ce) scintillator crystals have:
  • Mechanically robust characteristics and are non-hygroscopic
  • Stable scintillating characteristics up to c.100 rad
  • Virtually no afterglow emissions
  • No cleavage planes, so can me easily machined into various shapes and geometries

LuAP(Ce) 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
  • Are intrinsically radioactive making it unacceptable for some applications
  • Are susceptible to radiation damage, starting with doses between 1 and 10 Gray (10² - 10³ rad). Reversible with time or annealing.

LuAP(Ce) scintillator crystals are useful in diverse applications such as:
  • Positron Emission Tomography (PET)
  • Imaging screens
  • Specialist applications in high energy, nuclear, space and medical physics
