Combined Technology and Application of Trivista Laser Confocal Raman Spectrometer in Ferroelectric Ceramic Research

In this paper, the superiority of Raman spectroscopy and the characteristics of confocal micro Raman spectroscopy are briefly introduced. According to the demands of scientific research and test in the field of materials science, the in-situ observation application cases for PLZT ferroelectric ceramic materials under the external fields action of polarization field, force electric field and temperature field with the combined technology of mechanical devices for Trivista laser confocal micro Raman spectrometer in recent years are summarized, the micro structure's changes and fatigue damage mechanisms of PLZT ferroelectric ceramic materials under external fields are analyzed and discussed by obtained Raman spectra.
