Abstract
NBT-BT (sodium bismuth titanate-barium titanate) lead-free ceramics were prepared via the conventional solid-state reaction method in the Morphotropic Phase Boundary (MPB) composition. The prepared ceramics were irradiated with 100Â MeV O7+ ions using four different fluences of 5Â ÃÂ 1011, 1Â ÃÂ 1012, 5Â ÃÂ 1012 and 1Â ÃÂ 1013Â ions/cm2. The dielectric constants of the pristine and irradiated samples were determined from 300 to 623Â K for a broad range of frequencies from 20Â Hz to 2Â MHz. Irradiation with oxygen ions decreased the anti-ferroelectric temperature region present in the samples. The structural stability of the samples against the irradiation was investigated via XRD and Raman spectroscopy before and after the irradiation.
