RAMAN SPECTROSCOPY AS A METHOD FOR NANOSCALED STRUCTURAL INVESTIGATIONS

摘要

The advantage of the Raman spectroscopy as a method for studying nano-scaled atomic arrangements in the structure of complex materials is demonstrated on the basis of original spectroscopic data on microporous, ferroelastic and relaxor-ferroelectric materials. It is shown that the method is fairly applicable to analyzing structure perturbations in defected crystals, incipient structural species in crystallization processes, atomic arrangement across the domain walls, dynamic structural fluctuations and incipient ferroic clusters responsible for improper phase transitions.
