[20p-PB5-48] Characterizations of Nd-doped garnet crystals as scintillators
Keywords:scintillator, neodymium, garnet
We have grown and characterized Nd-doped garnet crystals (Y3Al5O12, Y3Al2Ga3O12, Gd3Al2Ga3O12, Lu3Al5O12, and Lu3Al2Ga3O12) as scintillators. All the samples exhibited luminescence due to the 4f-4f transitions of Nd3+, which appeared around 1050 nm. However, the scintillation intensity depnded on the host crystal, and it appeared to be in an order of LuAG>YAG>GAGG>YAGG>LuAGG.
