| 英文摘要 | Bismuth layer-structured ferroelectric (BLSFs) ceramics of Sr1-xEux Bi2Nb2O9 (SBT-xEu, x=0.000, 0.002, 0.004, 0.006) were prepared by a conventional solid-state reaction method. All the samples have a bismuth oxide layered structure with a dense microstructure. The ferroelectric, piezoelectric, dielectric and optical properties of the ceramics were investigated. After Eu3+ doping, samples show a bright red photoluminescence upon blue light excitation of the 400-500 nm. Upon the excitation of 465 nm light, the materials have two intense emission bands peaking around 593 nm (yellow) and 616 nm (red). Meanwhile, good electrical properties with large piezoelectric constant d(33) of 14 pC/N and large remnant polarization 2P(r) of 11.97 mu C/cm(2) are obtained at x=0.006. Moreover, this material has a high Curie temperature (T-c=429 degrees C) and high resistivity, which makes the material resistant to thermal depolarization up to its Curie temperature. This feature indicates that the SBN-xEu ceramics have a latent use in high temperature applications. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved. |
