- Analysis of the relative and absolute Raman intensity is very important and powerful tool which allows to understand and characterize the modifications of the crystal/amorphous structure due to: (i) changes of the symmetry, e.g. substitution of the B site ion by the rare earth/lanthanide one and incorporation of mobile species in the case of high temperature protonic conducting perovskites; (ii) changes of the short/long range order, e.g. existence/disappearance of the nanoregions in the case of $PbMg_{1/3}Nb_{2/3}O_{3-x}PbTiO_3$ (PMN-PT) relaxor ferroelectric perovskites; (iii) changes of the nanostructure, e.g. depolymerisation of the Si-O network due to the substitution of the $Si^{4+}$ ions (and associated covalent bonds) by the $M^+$ cations (forming ionic bonds) or by the incorporation of the metal nanoprecipitates in the case of glasses, glazes and enamels.
