摘要：

Here, the phase structure, microstructure, and electrical and luminescent properties of 0.93(Na0.5Bi0.5)(1-x)TiO3- 0.07BaTiO(3-)xEu(3+) (BNBT-xEu, 0.000 <= x <= 0.020) upon increasing the Eu3+ content, and the permittivity curve became broader, especially at a high doping content. The ferroelectric and piezoelectric properties were enhanced due to appropriate ratio of R and T phases, increased density, reduced Td, reduced EC, and reduced current density caused by Eu3+ doping. The maximum remnant polarization of Pr = 35.5 mu C/cm(2) and piezoelectric constant of d(33) = 214 pC/N were achieved for the x = 0.010 ceramic. Eu3+ doped BNBT ceramics exhibited red fluorescence at 614 nm derived from the D-5(0)-> F-7(2) transition of Eu3+ under 466 nm excitation. These results demonstrate the potential applications of the Eu3+ doped BNBT ceramics for novel integrated electronic devices.
