Na0.25K0.25Bi2.5-xHoxNb2O9 (NKBN-xHo3+, 0.000≤x≤0.030) bismuth layered ceramics were prepared by a conventional solid-state method. Effect of Ho3+ doping on the structural, electrical properties and up-conversion luminescence properties of NKBN ceramics was investigated. Based on the results by X-ray diffraction results, Ho3+ enters into the NKBN lattice and forms a solid solution. The grain size of NKBN samples decreases with the increased of Ho3+ doping. The optimum piezoelectric and ferroelectric properties of ceramic can be obtained as x=0.020, i.e., d33=21.8 pC/N, 2Pr=1.84 μC/cm2, where d33 is piezoelectric constant and Pr is remanent polarization. All the samples show little depolarization at 400 ℃, thus having a good thermal stability. Under the excitation of 980 nm laser, all the samples have the characteristics of up-conversion fluorescence luminescence, indicating that NKBN-xHo3+ ceramics can offer a potential application for optical-electrical multifunctional materials. The lattice structure symmetry of ceramic samples increases and the up-conversion fluorescence luminescence intensity reduces with the increase of polarization voltage.
