The luminescent and scintillation applications and materials science properties of YAIO3 and YAIO3:Ce single crystalline films grown by liquid phase epitaxy from BaO-based flux

Single crystalline films (SCFs) of undoped and Ce 3 +-doped YA10 3 (YAP) perovskite were crystallized by liquid-phase epitaxy method onto YAP substrates for the first time from the novel lead-free BaO-B 2 0 3 -BaF 2 fluxes. The absorption, luminescence, and scintillation properties of these films are measured and compared with the films grown from the standar Pb0-B 2 0 3 flux. It appears that the films obtained from the BaO-based flux exhibit better luminescent and scintillation properties with respect to films grown from the PbO-based one.
