Single crystal Ce doped scintillator material with garnet structure sensitive to gamma ray and neutron radiation

A mixed garnet scintillator host material is obtained from the melt—Yttrium Gadolinium Gallium Aluminum Garnet (YGGAG). In addition to the high thermal and chemical stability and radiation hardness found in garnet crystals, it offers sensitivity to neutrons due to the presence of Gd atoms, has lower melting temperature than yttrium aluminum garnet, and similar crystallization behavior suitable for growth of large volume crystals. Crystals of YGGAG doped with Ce of 10×10×10mm3 have already demonstrated energy resolution of 10% at 662keV. ► Scintillator host—Yttrium Gadolinium Gallium Aluminum Garnet is obtained from melt. ► It has sensitivity to neutrons, crystallization behavior suitable for large single crystal growth. ► Its scintillation output has a good spectral match for Si-PIN photodiodes. ► Ce doped YGGAG of 10×10×10mm3 demonstrated energy resolution of 10% at 662keV.
