英文摘要	Nitrogen-doped BaTiO3 (BT) ceramics were produced by the solid-state reaction method in conjunction with ammonia gas treatment. The optical absorption spectra results show that the bandgap of BT ceramic is narrowed after N-doping, suggesting that the N-doping is an effective route to increase light absorption. Polar properties measurements indicate that the ferroelectricity of BT ceramic is well maintained after the N-doping. In addition, the electric-field–induced strain is prominently improved to ~0.8% after N-doping, a value superior to that of PZT. Furthermore, the influence of N-doping on photoelectric properties of BT ceramics was also investigated. Large increase in photoconductivity and fast response to light illumination conditions were observed in N-doped BT ceramics. This work provides a novel route to enhance the (photo)electric properties of ferroelectric materials. © 2018 The American Ceramic Society
