In this paper, new lead-free luminescent ferroelectric materials, (Bi0.5Na0.5)0.935-xSmxBa0.065Ti1-xSbxO3 (BNT-0.065BT-xSmSb) ceramics, were prepared by introducing Sm/Sb. The influence of Sm/Sb on the phase structure, microstructure and electrical functions of BNT-0.065BT was systematically studied. BNT-0.065BT-xSmSb ceramics presented a pure perovskite phase structure. Doping with Sm/Sb induced a ferroelectric to relaxor phase transformation and thus promoted strain improvement. When x=0.004, the unipolar strain was 0.31% (70 kV/cm), equivalent to a large signal d33*(Smax/Emax) of 443 pm/V. Moreover, studies on the luminescence properties showed that BNT-0.065BT-xSmSb ceramics exhibited bright orange-red luminescence under 407 nm excitation. The luminescence intensity increased as the Sm/Sb doping concentration increased. The main emission peak was a strong red emission peak located near 599 nm, corresponding to the 4G5/2→6H7/2 transition. As multifunctional materials, BNT-0.065BT-xSmSb ceramics showed great latent capacity for optical-electrical integration and coupling device applications.
