Abstract

Abstract: The Pr 3+ d–f luminescence was investigated in the single crystalline films (SCF) of Lu3 Al5−x Gax O12 :Pr garnet solid solution at x = 1–3, grown by the liquid phase epitaxy (LPE) method from the melt-solution based on the PbO–B2 O3 flux. The shape of CL spectra and decay kinetics of Pr 3+ ions in Lu3 Al5−x Gax O12 SCFs strongly depend on the total gallium concentrationx and distribution of Ga 3+ ions between the tetrahedral and octahedral position of the garnet host. The best scintillation properties of Lu3 Al5−x Gax O12 :Pr SCF are achieved at the nominal Ga content in melt-solution in the x = 2–2.5 range. Highlights: Single crystalline films of Lu3 Al5−x Gax O12 :Pr garnet at x = 1–3 were grown by the LPE method. Pr 3+ emission spectra, light yield and decay time of films show strong dependence on Ga content. The maximal light yield of Lu3 Al5−x Gax O12 :Pr film is observed at Ga content x = 2.0–2.5.
