摘要：

Pr3+-doped SrBi2Nb2O9 (SBN) multifunctional ceramics were synthesized by the conventional solid state method. The photoluminescence (PL) excitation and emission spectra, enhanced ferroelectric and dielectric properties were investigated. The X-ray diffraction (XRD) and FESEM analyses indicated that the samples were simple phase and uniform flake-structure. Under the 250-350 nm ultraviolet (UV) excitations, the red emission was obtained and the optimal emission intensity was investigated when Pr doping level was 0.005 mol. With the increasing of the Pr3+ ion contents, the ferroelectric properties were enhanced obviously. As a new multifunctional material, the Pr3+-doped SBN ceramics could be used for a wide range of application, such as integrated electro-optical devices. (C) 2014 Elsevier Ltd. All rights reserved.
