Abstract

The effects of γ-ray, electron and neutron (fluences up to 2·10¹⁸ n/cm²) irradiation on extinction spectra and dielectric characteristics (hysteresis, thermal and frequency dependencies of dielectric permittivity ε and losses) in PLZT X/65/35 (X = 4.5-11 at.%) and PbSc_0.5Nb_0.5O₃ ceramics are analyzed with respect to composition, state of phase, and polarization by means of annealing in isochronic and prolonged time regimes. A gradual shift of extinction edge to longer wavelengths, reduction of polarization and ε values, and a progressive diffusion of the phase transition with the increase of irradiation fluence are observed in neutron irradiated PLZT ceramics.
