Abstract: In this paper, Pr3+ doped Na0.25K0.25Bi2.5Nb2O9 (NKBN-xPr3+) ceramics were successfully prepared via a conventional solid-state reaction process. The structural, dielectric, and piezoelectric properties as well as photoluminescence performance of the samples were systemically studied. All… read more here.

Abstract: The three different doped (Na, K and Mg) Na0.5Bi0.5TiO3 compounds were prepared. The grain conductivity of the doped Na0.5Bi0.5TiO3 compounds shows: Na-doping > K-doping > Mg-doping. Using the dielectric relaxation spectroscopy, the relaxation parameters can be obtained: ENa = 0.61 eV, EK = 0.64 eV… read more here.
