Cerium doped Yttrium Aluminum Garnet (Ce:YAG) Single Crystal Substrates
Cerium doped YAG is a scintillator crystal and phosphor material. The wavelength of the maximum emission at 550nm is well matched to CCD sensitivity. YAG(Ce) is a reasonably fast scintillator with a relative light yield of 21% of NaI(Tl). YAG(Ce)'s light yield increases linearly with the total energy of the electron beam.
