摘要：

Lead-free (1 - x)Na0.5Bi0.5TiO3-xBa(Zr0.05Ti0.95)O-3:Pr (NBT-xBZT: Pr, x = 0-0.12) were synthesized by conventional solid state method. The influence of Ba(Zr0.05Ti0.95)O-3 (BZT) content on the piezoelectric and photoluminescence performance was investigated. The results show that all ceramics exhibit strong red emission at 607 nm, and the NBT-0.07BZT:Pr ceramic shows the optimal photoluminescence property. In addition, piezoelectric performance is also enhanced with the increasing of BZT fraction, and reaches the maximum value at x = 0.07. The results show that the Pr3+ ions emission may be used as a probe for the phase transition of the ferroelectric materials. (C) 2013 Elsevier B.V. All rights reserved.
