AbstractThe vibrational characteristics of uniform SnO2 powders consisting of particles of various shapes (spherical, prismatic, rodlike) and of different size distributions were studied by infrared and Raman spectroscopy. The infrared spectra of the samples displayed variations in the position, relative intensity and width of the absorption bands, which were attributed to particle shape effects. The Raman spectra showed a weakening of the intensities of the single-crystal SnO2 modes as the crystallite size decreased. In addition, the spectra of all studied samples also exhibited some bands not predicted by group-theory considerations, the origin of which was related to the particle surface. A detailed vibrational study provides information on the particle shape and size and the crystallinity of powdered materials. © 1993.
