Ce: GAGG crystal (chemical formula Ce: Gd3Al2Ga3O12) is a scintillation crystal excellent scintillating performance. Which exhibits stable physical and chemical properties, high thermal conductivity. The effective atomic number of the GAGG crystal is as high as 54.4, and the peak wavelength of the emission spectrum located at 520nm, which matches well with the sensitive wavelength range of the photomultiplier tube (PMT) and silicon photodiode (PD). Ce: GAGG crystals are widely used in photomultiplier tubes, photoelectric counters, scintillation screens and other high-energy particle detection. Such as β-rays, γ-rays, CT, scanning electron microscope (SEM) and and positron emission tomography (PET).
CRYLINK has developed 2 kinds of GAGG(Ce) crystal, with faster decay time(GAGG-K), with high light output(GAGG-G) for the customer in different field.
