Description

Gd3Sc2Ga3O12 doped with Ca, Mg, and Zr (GSGG:Ca,Mg,Zr) is a single crystal substrate that has been developed as a scintillator material for gamma-ray detection. The addition of Ca, Mg, and Zr in GSGG improves its scintillation properties, such as light yield, energy resolution, and decay time, making it suitable for high-energy physics experiments, medical imaging, and nuclear radiation detection. GSGG:Ca,Mg,Zr has a cubic crystal structure with lattice parameters of a = 12.414 Å and a refractive index of about 1.94 at 1064 nm wavelength. Its melting point is around 1870 °C, and its density is about 7.08 g/cm3.
