摘要：

The effects of gamma-ray, electron and neutron (fluences up to 210(18) n/cm(2)) irradiation on extinction spectra and dielectric characteristics (hysteresis, thermal and frequency dependencies of dielectric permittivity epsilon and losses) in PLZT X/65/35 (X=4.5-11 at%) and PbSc0.5Nb0.5O3 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 epsilon values, and a progressive diffusion of the phase transition with the increase of irradiation fluence are observed in neutron irradiated PLZT ceramics.
