Additional Information
LYSO is a very special synthetic material. Chemically, it is a transitional series crystal of YSO and LSO. Varying amounts of the compounds and ions exist throughout the crystal structure. This material has optimal properties for precision scintillation. Accordingly, it's one of the most effective luminescent materials. It is often found in use of Gamma Sensor Arrays.
Variants and Types
Ce:LYSO
Ce:LYSO
Color: Colorless
Fluorescence: Blue
Cause: Cerium Ions
Used for Gamma Arrays, Sensors
Production and Synthesis
Czochralski Method
Czochralski Method
Involves pulling a crystal (boule) upward from a molten solution. Produces some of the purest crystals but requires a cleanroom environment.
