Structural, optical and luminescent properties of undoped Gd3AlxGa5-xO12 (x = 0,1,2,3) and Gd2YAl2Ga3O12 single crystals

Ho3+ codoping of GGAG:Ce: a detailed analysis of acceleration of scintillation response and scintillation efficiency loss

“…[27][28][29][30] Other codopants were studied for this purpose as well. 31 Dependence of the bandgap value on the host composition was also studied 32,33 and garnet compounds luminescence and scintillation characteristics were reviewed in ref. 34.…”

Bulk Single-Crystal Growth of Ce/Gd3(Al,Ga)5O12 from Melt without a Precious Metal Crucible by Pulling from a Cold Container

“…In the past decade, single-crystal Ce-doped Gd 3 (Al,Ga) 5 O 12 (Ce/GAGG) has been found to be an excellent scintillator material with its characteristics continuously studied by many laboratories regarding both fundamental physical processes and application potential of these scintillators. − We had previously reported the use of the Czochralski (CZ) technique to successfully grow Ce/GAGG crystals with a diameter of up to 3–4 in. , However, as is the case for many other oxide scintillators, the mass production of Ce/GAGG is difficult because of its high melting point. In most cases, one must either use a precious metal as the crucible material or heat the scintillator material indirectly.…”

The Influence of Halide Ion Substitution on Energy Structure and Luminescence Efficiency in CeBr2I and CeBrI2 Crystals

“…An increase in light yield was observed for (Lu,Y)AP:Ce mixed crystals with an intermediate concentration of Lu/Y [ 18 ] and for Gd 3 (Al,Ga) 5 O 12 crystals (GAGG) with an Al/Ga ratio of 2/3 [ 19 ]. Mixed oxide scintillators LYSO demonstrate a 10–30% higher light output [ 20 , 21 ].…”
