Abstract

AbstractIn this work, scintillation properties of Ce1%, Pr1%, Eu1% and non‐doped La3‐xLu2+xGa3O12 (LLGG) single crystals were evaluated. At first, in order to investigate single phase region of La3‐xLu2+xGa3O12, crystal growth was carried out for undoped LLGG crystal. After that, Ce1%, Pr1% and Eu1% doped La2.5Lu2.5Ga3O12 crystals were grown by the μ‐PD method. Radioluminescence spectra and photoluminescence decay curve of these crystals ware measured. Energy spectra were collected under 5.5 MeV α‐ray excitation (241Am source) and detected by an PMT R7600U (Hamamatsu) in order to determine light yield. (© 2012 WILEY‐VCH Verlag GmbH & Co.
