The luminescent and scintillation properties of YAlO3 and YAlO3:Ce single crystalline films grown by liquid phase epitaxy from BaO-based flux

Authors


Abstract

Single crystalline films (SCFs) of undoped and Ce3+-doped YAlO3 (YAP) 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 scintillation properties with respect to films grown from the PbO-based one.
