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 2 O 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 2 O 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.
