YSO(Ce) Scintillation Crystals
YSO(Ce) - Yttrium Orthosilicate:Cerium (Y₂SiO₅:Ce) - scintillation crystals are relatively bright, have an emission maximum at 420nm and are relatively fast with a decay time of c.60ns.

YSO(Ce) scintillator crystal strengths:
  • Reasonably good stopping power with a density of 4.5g/cm³
  • Fast decay time of 50 - 70ns
  • Good rad-hard properties
  • No background radiation
  • Mechanically robust characteristics, no cleavage planes and are non-hygroscopic.

YSO(Ce) scintillator crystals issues to be noted:
  • TBA

Yttrium Orthosilicate:Ce - YSO(Ce) scintillator crystals are useful in diverse applications such as:
