Ce:GAGG

Description

Cerium-doped gadolinium aluminium gallium garnet (Ce:GAGG) is a relatively new single crystal scintillator with several interesting properties, such as very high light yield, high density, good energy resolution, an emission peak well-matched to silicon sensors, and low intrinsic energy resolution. Moreover, the material is nonhygroscopic and non-selfradiation. It will be widely used in PET, PEM, SPECT, CT, X-ray &Gamma ray detection.

 

Features

  • Relatively bright – emitting >50,000 photons/MeV

  • Good absorbers with good stopping powers - density 6.63 g/cm³

  • Broadly emitting with a 540nm peak

  • Good Energy resolution


Application

  • CT

  • PET

  • SPECT

  • LED lighting

  • Laser lighting

  • Particle accelerator
