LYSO(Ce) Scintillation Crystal
LYSO(Ce) crystal (Lu1-xYxSi2O5) has high density, high light output, short decay time, good radiation hardness and an emission wavelength of 420 nm. These characteristics make it an ideal material for a wide variety of applications such as Industrial and medical CT, PET, and nuclear physics.
Advantage:
- High density
- Fast, single exponential decay time
- Non-hygroscopic
Compared to BGO:
- 3-4x the light yield
- 6-7x faster decay time
- Better energy resolution
