Advantages and developments of Raman spectroscopy for electroceramics

Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectroscopy in this class of materials. In this review, we outline the fields of application of Raman spectroscopy and microscopy in various electroceramic systems, defining current key bottlenecks and explaining promising recent developments. We focus our attention on recent experimental developments, including coupling Raman spectroscopy with other methodologies and modelling approaches involving both the model-based data interpretation and the ab initio calculation of realistic Raman spectra.
