YAG(Ce) Scintillator


YAG(Ce) - Yttrium Aluminum Garnet doped with Cerium – (chemical formula Y3Al5O12(Ce)) is a non-hygroscopic, chemically inert inorganic scintillator. The wavelength of the maximum emission at 550nm is well matched to CCD sensititivty. YAG(Ce) is a reasonably fast scintillator with a relative light yield of 21% of NaI(Tl).

YAG (Ce) scintillator offers imaging solutions in Scanning & Transmission Electron Microscopes (SEM / TEM) and more recently for high resolution x-ray imaging on experiments at the new generation of synchrotrons.

Features & Benefits

  • High electron conversion efficiency
  • Good resolution
  • Light yield increases linearly with the total energy of the electron beam
  • Good thermal conductivity
