| Abstract: | The fractal property and low frequency Raman scattering of Eu(DBM)3 nanosized microcrystals were investigated. The influence of the fractal structure of Eu(DBM)3 non-crystalline solids on low frequency scattering was studied. It was found that vibrational excitations ou the fractal are localized and can be described in terms of fraction8. It was sliown that reduced Raman scattering intensity is of a power law dependence of the vibrational frequencies for all samples.The fractal and spectraJ dimensiou were also determined, we found that our experimental value was in fair agreement with the theoretical one. |
