Ultraviolet-light-induced multi-physics behaviors of 0–3 polarized transparent PLZT plates: I. Experimental testing

This paper presents a novel experimental and numerical investigation into ultraviolet-light-induced multi-physics responses of 0–3 polarized PbLaZrTi (PLZT) plates with transparent indium tin oxide (ITO) electrodes on both surfaces. Part I details the testing set-up, procedure and results for the 0.3 mm thick PLZT sample polarized at room temperature and an electrical field strength of 1200 V mm−1. The measured time-dependent curves and steady state results are presented for the photo-induced electrical voltage and current, temperature and transverse displacement of a 0–3 polarized PLZT plate with double-sided ITO electrodes. It is worth noting that there exists no report on the measurement of transverse displacements of 0–3 polarized PLZT plates, which plays an important role in validating the novel finite element formulation for their multi-physics fields in part II
