Growth and luminescent properties of (Lu–Y)AlO3:Ce single crystalline films

The work is dedicated to the development of scintillating screens based on single crystalline films (SCF) of Ce doped Lu–Y–Al perovskites grown by the liquid phase epitaxy method. We show in this work that Lu1−xYxAP:Ce SCF with very good structural and optical perfection can be grown from the PbO-based flux onto YAP substrates in all range of x-values. We also found the Lu1−xYxAP:Ce SCF can be crystallized by LPE method from the lead free BaO–B2O3–BaF2 flux onto YAP substrates in the range of x values up to 0.4 formula units.
