A large and reversible upconversion (UC) luminescence modulation has been found in the Na0.498Bi0.498TiO3:0.002Er (NBT:0.002Er) based on the photochromic reaction. The dependence of luminescence modulation of the ceramics on the wavelength of irradiation light and sintering temperature was investigated. It was found that the optimized sintering temperature and irradiation wavelength were 1130°C and 405 nm, respectively. The highest ΔRt (defined as: ΔRt = (R0 – Rt)/R0×100(%), where R0 and Rt are the initial emission intensity and that after different irradiation time, respectively) value of 44.9% was obtained for the ceramics sintered at 1130°C after irradiation at 405 nm. More importantly, for the poled ceramics, ΔRt value was promoted to a high value of 75.5%, which was 168% of that of the unpoled ones. The mechanism of luminescence modulation and its enhancement via electric field poling were discussed. This study demonstrated that electric field poling was an effective strategy to enhance the PC reaction in the NBT ceramics.

The Eu3+‐modified Bi0.5Na0.5TiO3 (BNT) ceramics have been fabricated by the solid‐state reaction method. The impact of Eu3+ doping on the structure, photoluminescence, and electrical properties has been studied by XRD, SEM, PL spectra, and LCR meter. X‐ray diffraction analysis reveals that the crystal structure of the samples is well matched with the trigonal perovskite, and the optimal temperature of presintering is 880°C. The Eu3+‐doped BNT ceramics show excellent red fluorescence at 614 nm corresponding to the 5D0→7F2 transition of Eu3+ under 466 nm excitation and relatively long fluorescence lifetime. The BNT‐0.02Eu ceramic density is up to 5.68 g/cm3 and the relative density is up to 94.6% with sintering temperature 1075°C. The piezoelectric constant (d33) of samples has been significantly improved up to 110 pC/N by Eu3+ doping. The BNT‐0.03Eu ceramic presintered at 880°C and sintered at 1050°C has good dielectric properties and excellent luminescence properties. Eu3+‐doped BNT ceramics make it potential applications for novel integrated electro‐optical and multifunctional devices.
