Na0.5Bi4.5-x(Sm0.5Ce0.5)xTi4O15 (NBT-x(Sm, Ce) bismuth-layered lead-free piezoelectric ceramics were fabricated by a solid-state synthesis method, and the influence of (Sm0.5Ce0.5)3+ additive on the structure and electrical/photoluminescence properties of samples was investigated. For the ceramics modified by (Sm0.5Ce0.5)3+ dopants, the phase structure and microstructure have little changes. The electrical properties of ceramics are enhanced. As x=0.008, the remnant polarization 2Pr reaches 13.33 μC/cm2, and a high Curitemperature TC is 640 ℃. After (Sm0.5Ce0.5)3+ doping, the ceramics show a bright orange photoluminescence. The more intense emission band at 597 nm appears under an excitation at 407 nm, corresponding to the 4G5/2→6H7/2 energy level transition. As a multifunctional material, (Sm0.5Ce0.5)3+-modified NBT piezoelectric ceramics have promising application prospects in optoelectronic devices, sensors, etc..
