2inch diameter single crystal growth and scintillation properties of Ce:Gd3Al2Ga3O12

High-photon-yield scintillation detector with Ar/CF4 and glass gas electron multiplier

“…First, a 5 mm cubic CsI(Tl) crystal was calibrated for the reference number of scintillation photons. 22) Next, the number of photons emitted from the scintillating G-GEM was estimated by comparison with the calibrated CsI(Tl) crystal. A schematic of the measurement setup is shown in Fig.…”

Development of transparent ceramic Ce-doped gadolinium garnet gamma spectrometers

“…Although high light yields and good energy resolution in small single crystal samples have been obtained for Ce-doped Gd-garnets recently, large size crystals exhibit significant Ce gradients, resulting in light yield non-uniformity and impacting the performance for gamma spectroscopy [8].…”

Microstructure and optical characteristics of Ce:Gd3(Ga,Al)5O12 ceramic for scintillator application

“…To the best of our knowledge, there are mainly three ceramic scintillators used in current medical CT detectors, namely, (Y,Gd) 2 O 3 :Eu,Pr, Gemstone TM (a cerium doped garnet) and Gd 2 O 2 S:Pr,Ce,F. Cerium doped gadolinium gallium aluminum garnet (Ce:GGAG) scintillators have shown potential of applications in CT or high-energy particle detectors due to their attractive characteristics, such as high density (6.63 g/cm 3 ), high light yield (70,000 ph/MeV), short primary decay time (52.8 ns), and excellent energy resolution (8.3% at 662 keV) [1][2][3][4]. Among the chemical elements of GGAG, Ga 3 þ not only plays an important role in stabilizing the crystal structure, but also adjusts the energy level of the host and Ce 3 þ .…”
