Characterization of P(L)ZT Ceramics by Modulated Optical Spectroscopy

Abstract

The purpose of this investigation is to study and develop non-destructive, simple, and rapid methods for measuring the structural and dynamic properties of ferroelectric ceramics. Optical modulation techniques, particularly electric field modulated transmission and reflectivity have been shown to be powerful tools for investigating the electronic properties of solids. By modulating an internal parameter such as electric field (electroreflectance and electrotransmission) it is possible to obtain derivative-like enhancements of optical structures related to interband transitions. In Section 2 characterization of transparent PLZT ceramics by modulated optical spectroscopy and in Section 3 an electroreflectance study of opaque PZT ceramics are presented.
