Single crystalline films of undoped and Ce3 -doped YAlO3 perovskite were crystallized by liquid-phase epitaxy method onto YAP substrates for the first time from the novel lead-free BaO-B2O3-BaF2 fluxes. The absorption,luminescence, and scintillation properties of these films are measured and compared with the films grown from the standard PbO-B2O3 flux.
It appears that the films obtained from the BaO based flux exhibit better luminescent and cintillation properties with respect to films grown from the PbO-based one.
