Crystal growth, optical properties, and α-ray responses of Ce-doped LiCaAlF6 for different Ce concentration

Ionizing radiation induced emission: Scintillation and storage-type luminescence

“…To investigate further about ionizing radiation induced luminescence, in this time, I evaluated scintillation, OSL, and TSL properties of Eu-doped (1, 2, 3, and 4%) LiCaAlF 6 [7,8], Ce-doped (2, 3, and 4%) LiCaAlF 6 [9,10], and Pr-doped (0.25, 0.3, 0.4, 0.6, 0.8, and 1%) LuAG [11,12] on a comparison with previously studied Ce-doped CaF 2 [6]. LiCaAlF 6 crystals were fabricated by Tokuyama Corp. and these materials became commercially available products.…”

Dopant segregation in rare earth doped lutetium aluminum garnet single crystals grown by the micro-pulling down method

“…It requires small amount of raw materials for one crystal growth process; typically less than 1 g. In addition, the growth speed is higher than that of conventional methods such as Czochralski (CZ), Bridgeman, and Floating Zone (FZ) methods [1]. Many novel oxide and fluoride single crystalline scintillators have been developed by the m-PD method like Pr-doped lutetium aluminum garnet (Pr:LuAG) and Ce or Eu-doped 6 lithium calcium aluminum fluoride (Ce: 6 LiCAF, Eu: 6 LiCAF) single crystals [2][3][4][5][6].…”

Growth and characterization of Ce-doped Ca3(BO3)2 crystals for neutron scintillator

“…Undoped crystal indicated high transmittance in this range, while Ce-doped crystal showed two absorption band around 275 and 345 nm, which corresponds to the transition from the 4f ground state levels of 2 F 5/2 and 2 F 7/2 to Ce 3 + 5d excited state. Another absorption band around 200-260 nm may be attributed to defects of charge compensation, which is due to Ce 3 + ion located on the divalent Ca sites [18][19].…”
