The Relationship

The lead-free multifunctional ceramics Sm3+-doped (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 were synthesized via conventional sintering. The influences of Sm3+ concentration on phase structure, grain size, Curie temperature, ferro-/piezoelectric properties, as well as photoluminescence (PL) performances of the ceramics have been investigated. The results show that with the Sm3+ concentration of 0.4[Formula: see text]mol%, the integrated optoelectronic performances are best. In order to further study the relationship between ferroelectric and PL features, the poling effect on PL intensities of the ceramics has been focused on, giving the highest enhancement factors of 52.6% induced by both lattice distortion and phase transformation. The electric poling is an effective route to enhance the PL performance of luminescent ferroelectrics.

Dielectric And Piezoelectric Properties

Lead-free (1-x-y)Na1/2Bi1/2TiO3-xBaTiO3-yBiFeO3 ceramics were synthesized by ordinary sintering technique. The compositional dependence of phase structure and electrical properties of the ceramics was systematically investigated. All samples possessed pure perovskite structure. The dielectric and piezoelectric properties of ceramics were investigated with the amount of different BiFeO3 substitutions. The addition of BiFeO3 can not only decrease Ec and Pr but also lead to a significant degradation of the dielectric loss tanδ.

(1-x)(0.64PNN-0.36PT)-x(0.91PZN-0.09PT) ferroelectric ceramics with different x were synthesized by the columbite precursor method. The phase structure and piezoelectric properties were investigated. XRD profiles implied that with the increasing of x, samples could no longer maintain the pure perovskite phase. All the compositions were found to lie within the region of the morphotropic phase boundaries (MPBs) with different contents of rhombohedral and tetragonal phases. The piezoelectric coefficients for compositions with x £ 0.30 were obviously better than those for the rest ones and the composition with x = 0.15 exhibited the largest value of d33 among all the samples. The relationship between the structure and the piezoelectric properties was discussed.
