Ce: LuAG Scintillation Crystal Cerium doped Lutetium Aluminium High-density Fast decay time PET

Description of LuAG(Ce) Scintillation Crystals:

Lutetium Aluminium Garnet (LuAG(Ce) - Lu3Al5O12:Ce) scintillator crystals are relatively dense (6.73g/cm³), have a high Z (58.9), and have a fast decay time (70ns). With a peak emission of 535nm, LuAG(Ce) output is well matched to photodiodes avalanche photodiodes APDs and silicon photomultipliers (SiPMs). In addition, these crystals have good temperature properties. LuAG crystal is a specific type composed of lutetium aluminum garnet (LuAG) doped with cerium Ce or Pr ions. LuAG is a synthetic crystalline material known for its excellent scintillation properties and is widely used in various radiation detection applications.

The character of LuAG(Ce) Scintillation Crystals:

High density
Fast decay time
The wavelength of luminescence emission is well suitable for Photodiode and Avalanche Diode readout
Chemical and mechanical resistance
Temperature resistance

Mechanically robust characteristics and are non-hygroscopic
