Raman Scattering from ZnO(Fe) Nanoparticles (original) (raw)
2008, Acta Physica Polonica A
Nanocrystalline samples of ZnO(Fe) were synthesized by wet chemical method. Samples were characterized by X-ray diffraction to determine composition of the samples (ZnO, Fe2O3, ZnFe2O4) and the mean crystalline size (8-52 nm). In this paper we report the experimental spectra of the Raman scattering (from 200 to 1600 cm −1). Main characteristics of experimental Raman spectrum in 200 to 1600 cm −1 spectral region are: sharp peak at 436 cm −1 and broad two-phonon structure at ≈ 1150 cm −1 , typical of ZnO; broad structure below 700 cm −1 that has different position and shape in case of ZnFe 2 O 4 or Fe 2 O 3 nanoparticles.
