Ce:YAP Scintillation Crystal

As scintillator crystal, Ce: YAP (Yttrium Aluminum Perovskite activated by Ce3+) shares the same advantages as YAG but is more efficient in terms of light output. As well. the emission spectrum peaks at about 378nm. and this corresponds closely to the maximum sensitivity of the S11 photocathode which in general is used in most scanning electron microscopes. (There would be more improvement in signal by using a YAP crystal rather than YAG in these microscopes). The decay time of YAP (40ns) is faster than YAG (80ns) so its overall performance is superior to YAG. YAP crystals are coated with 50nm of aluminum prior to use.

*P47: Scintillators for Scanning Electron Microscopes
They are coated with a thin layer of well selected P47 phosphor (Y1Si2O7:Ce3+; yttrium silicate activated with cerium). and have a high signal output and a good working life. They need not be coated with aluminum prior to use unless cathodoluminescence studies are required.

Ce:YAG Scintillation Crystal

Cerium-doped YAG is commonly used as a phosphor in cathode ray tubes and white light-emitting diodes, and as a scintillator. As scintillation crystal, Ce:YAG has a high luminous efficiency and wide pulse. Ce:YAG's emission peak (550nm) is well matched with the sensitivity wavelength of photodiode. Ce:YAG is a suitable scintillator when use photodiode as a photodetector for detecting light charged particles. Ce:YAG has good stable thermodynamic properties and can be applied in high temperature and extreme environments.
