Abstract
Knowledge of grain size and domain structure is essential to understanding the electro-optical properties of ferroelectric lead lanthanum zirconate titanate (PLZT) ceramics. In this paper, a nondestructive technique for studying the grain size and domain structure is presented. This technique takes advantage of the generation of photo-carriers to reduce silver ions adsorbed on grain and domain boundaries. The results of using this technique to decorate randomly poled PLZT are discussed and compared to conventional acid etching techniques.
