Crystal growth and characterization of Tm doped mixed rare-earth aluminum perovskite

Structure and scintillation yield of Ce-doped Al–Ga substituted yttrium garnet

“…A series of new efficient scintillators has been developed recently on the base of mixed crystals. Among the examples one can note solid solutions of oxide scintillators, such as Lu 2x Y 2À2x SiO 5 :Ce (LYSO) [1], Lu 2x Gd 2À2x SiO 5 :Ce (LGSO) [2], Lu x Y 1Àx AlO 3 :Ce (LuYAP) [3], Lu x Gd y Y 1ÀxÀy AlO 3 :Tm [4] (Lu x Gd 1Àx ) 3 (Al y Ga 1Ày ) 5 O 12 :Ce (LuGAGG) [5], based on isovalent substitution of host cations. In LYSO and LGSO crystals the Lu 3+ substitution by Y 3+ , or Gd 3+ improves energy resolution and suppresses afterglow [1,2].…”
