Modification of Lattice Vibrations Spectrums in the Nanoparticles of Paradibrombenzol/Paradihlorbenzol Solid Solution

Abstract

Using Raman scattering, the solid solution nanoparticles of paradibrombenzol/paradihlorbenzol are investigated. It is found that in a spectrum of nanoparticles of solid solution frequencies of spectral lines are reduced in comparison with similar lines of a single crystal with the same concentration of components. Calculations of the lattice oscillations by Dyne's method are performed. It is shown that these modifications of frequencies can be caused by the increase of lattice parameters with the reduction of nanoparticles sizes.
