Cerium doped Gadolinium Aluminium Gallium Garnet Crystal Description
Cerium doped Gadolinium Aluminium Gallium Garnet Crystal (Ce:GAGG) is a newly developed scintillator crystal used in single-photon emission computed tomography (SPECT), gamma-ray, and Compton electron detection. It is one of the brightest available scintillators with an emission peak of 520nm.
It is a relatively new single crystal scintillator with many properties, such as high light yield, high density, good energy resolution, good emission peak matching with silicon sensor and low intrinsic energy resolution. in addition, the material is non-hygroscopic and non-self-radiative. which is widely used in PET, PEM, SPECT, CT, X and y-ray detection and so on.

Cerium doped Gadolinium Aluminium Gallium Garnet Crystal Applications
It is used for single-photon emission computed tomography (SPECT) as well as gamma-ray and Compton electron detection. Cerium-doped GAGG crystals have many properties that make them suitable for gamma spectroscopy and medical imaging applications. A high photon yield and emission peak around 520 nm make the material well suited for readout by silicon photomultipliers (SiPM).
