Raman Scattering Studies of Microcrystalline V6O13

V6O13 microcrystalline powder was studied in an effort to resolve the stoichiometric effects. The Raman scattering spectrum of stoichiometric V6O13 microcrystalline powder is reported. The results are compared to the Raman scattering spectrum of V2O5 and VO2 polycrystalline materials obtained by annealing V6O13. Nous etudions les proprietes vibratoires du compose stoechiometrique V6O13 sous forme de poudre microcristalline. Le spectre de diffusion Raman est presente. Une comparaison est menee avec les spectres des composes V2O5 and VO2 polycristallins obtenus par traitement thermique de V6O13.
