  ABSTRACT: The structural and thermal properties of yttrium-aluminum-gadolinium-gallium (Y2.97Gd0.03Al2Ga3O12) single crystals doped with terbium (0.1%), cerium (0.01%) and co-doped with both terbium and cerium ((0.1, 0.01)%) were investigated. All samples were heated (calcined) at 1400°C for 15 hours before crystallization. X-ray powder diffraction (XRD) patterns of all calcined samples showed the presence of yttrium gallium aluminate (Y3Al2Ga3O12) and gadolinium gallium oxide (Gd3GaO6) while the grown crystals were single phase of Y3Al2Ga3O12. The lattice parameter of the crystals decreased with Ce doping. The thermal conductivity of each sample was determined from 25°C to 300°C and found to decrease exponentially with increasing temperature. All doped crystals have different thermal conductivity, which is attributed to the crucial influence of crystals structures. 0.01% Ce:YAGG was found to be a strong candidate for scintillators and other lasing materials because of its good thermal behavior (10.71 W/m·K).
