The luminescent and scintillation properties of YAlO 3 and YAlO 3:Ce single crystalline films grown by liquid phase epitaxy from BaO-based flux

Abstract

Single crystalline films (SCFs) of undoped and Ce 3+-doped YAlO 3 (YAP) perovskite were crystallized by liquid-phase epitaxy method onto YAP substrates for the first time from the novel lead-free BaO-B 2O 3-BaF 2 fluxes. The absorption, luminescence, and scintillation properties of these films are measured and compared with the films grown from the standard PbO-B 2O 3 flux. It appears that the films obtained from the BaObased flux exhibit better luminescent and scintillation properties with respect to films grown from the PbO-based one. © 2009 WILEY-VCH Verlag GmbH & Co.
