Abstract

The use of the vibrational spectroscopy techniques (Raman and infrared) in the characterization of nanostructured materials is presented. The Raman spectroscopy method has been used for structural characterization of nanomaterials. The estimation of average grain size and size distribution, layer thickness, strain effects, presence of defects and nonstoichiometry by Raman spectroscopy is illustrated in the case of CeO2, TiO2, and ZnO nanopowders, as well as nanostructured ZnSe/SiOx multilayers. The infrared spectroscopy method has been applied on TiO2 and ZnO nanopowders and SiOx thin films in the analysis of grain size and shape, porosity, the nature of the surface bonds and reactions at the nanoparticle surface..
