摘要：

The Pr3+ d-f luminescence was investigated in the single crystalline films (SCF) of Lu3Al5-xGaxO12:Pr garnet solid solution at x = 1-3, grown by the liquid phase epitaxy (LPE) method from the melt-solution based on the PbO-B2O3 flux. The shape of CL spectra and decay kinetics of Pr3+ ions in Lu3Al5-xGaxO12 SCFs strongly depend on the total gallium concentration x and distribution of Ga3+ ions between the tetrahedral and octahedral position of the garnet host. The best scintillation properties of Lu3Al5-xGaxO12:Pr SCF are achieved at the nominal Ga content in melt-solution in the x = 2-2.5 range. (C) 2016 Elsevier Ltd. All rights reserved.
