Abstract

Single crystalline films (SCF) of Lu 2SiO 5 (LSO) and Lu 2SiO 5:Ce (LSO:Ce) silicates with thickness of 2.5–15 μm were crystallized by liquid phase epitaxy method onto undoped LSO substrates from melt-solution based on PbO–B 2O 3 flux. The scintillation and luminescence properties of LSO:Ce SCF were compared with the properties of LSO:Ce single crystal. The peculiarities of luminescence properties of LSO:Ce SCF in comparison with crystal analog can be due to different distribution of Ce 3+ over the Lu1 and Lu2 positions of LSO host and are further influenced by Pb 2+ flux-originated contamination.
