Raman Spectra from Laser-Processed Lead Zirconate Titanate (PbZr 0.3 Ti 0.7 O 3 ) Prepared by a Sol-Gel Process

Abstract

We report on investigations of laser-induced crystallization of PbZr_0.3Ti_0.7O₃ (PZT) gel-powder. By means of micro-Raman spectroscopy, and of optical and scanning electron micrography (SEM), we show that, upon laser irradiation, amorphous PZT material is transformed into microcrystals of the perovskite structure. It was found that the laser-induced crystallization is much faster than crystallization through calcination in a conventional oven.
