“…While the MicroFC is not the best spectral match to Ce:GAGG, the peak optical response of the MicroFC occurs at 420nm compared with the emission peak of 520nm for Ce:GAGG, the device has significantly lower noise performance (dark rate) than similar devices with peak sensitivity in the green [27]. The MicroFM has a peak response of 500nm and is therefore a better spectral match to Ce:GAGG.…”

Abstract-Scintillators are a critical component of sensor systems for the detection of ionizing radiation. Such systems have a diverse portfolio of applications from medical imaging, well logging in oil exploration and detection systems for the prevention of the illicit movement of nuclear materials. The rare earth element cerium is an ideal dopant for a variety of host scintillating materials due to the fast 5d1 → 4f radiative transition of Ce 3+ . Cerium-doped Gadolinium Aluminium Gallium Garnet (Ce:GAGG) is a relatively new single crystal scintillator with several interesting properties. These include high light yield; an emission peak well-matched to silicon sensors; and a low intrinsic energy resolution. Moreover, the material has a high density and is non-hygroscopic. In this article we review the properties of cerium-doped GAGG and report Energy Resolution (ER) measurements over the temperature range -10• C to +50• C for 3 × 3 × 30 mm 3 Ce:GAGG crystals optically coupled to a Silicon Photomultipler (SiPM) sensor with a 3mm × 3mm active area. In addition the linearity of the scintillator-SiPM response as a function of gamma energy is reported.

Scintillation materials capable of transforming absorbed high-energy particles into visible radiation photons find multiple applications including advanced medical visualization methods. Gd3Al2Ga3O12 : Ce is a promising oxygen-containing sсintillator for fabrication of detecting crystals of positron emission tomographs due to its unique properties, e.g. high density, high light yield, radiation hardness etc. However its kinetic parameters currently restrict its use in this field. Attempts at improving the luminescence rise and decay time kinetics by introducing additional impurities have become a top priority task for many researchers. Analyzing literary data one can conclude that the optical parameters of co-doped crystals have been studied insufficiently or have not been studied at all. We have studied Ca2+ and Zr4+ co-doped Gd3Al2Ga3O12 : Ce single crystals by optical spectroscopy in the 200–2200 nm. We have taken the optical transmittance, absorption and reflection spectra and measured the refractive indices. Dispersion curves have been obtained by approximation of experimental refractive indices using the Brewster method and the Cauchy equation. Material constants of these equations have been estimated for each of the co-doped crystals.
