TLDR
In this paper, photorefraction (PR) is observed in prepolarized TFC in the absence of applied field throughout the ferroelectric state and in an applied field PR is observed over a wide interval of temperature around a diffuse phase transition.Abstract:
Transparent ferroelectric ceramics (TFC) of the PLZT X/65/35 type (La- doped lead zirconate-titanate, where X is the lanthanum concentration in at.%, 65/35 is the Zr/Ti ratio) display photoconductivity [1], the photovoltaic (PV) effect [2,3] and a pronounced electrooptic effect. For this reason photorefraction (PR) is observed in prepolarized TFC in the absence of applied field throughout the ferroelectric state. In an applied field PR is observed over a wide interval of temperature around a diffuse phase transition, as well as in the ferroelectric state.read more

Photo-induced light scattering in PLZT-10/65/35 ceramics
TL;DR: In this article, the angular and time dependence of the initial scattering and polarization-isotropic photo-induced light scattering as well as the intensity of the primary (pump) beam were investigated in PLZT 10/65/35 (Pb0.9La0.65Ti0.35)0.975O3) both experimentally and theoretically as functions of light intensity, external electric field and the thickness.
