•ZnO doped with Fe2O3, samples were prepared by calcination method.•Coexistence of phases Fe2O3 and ZnFe2O4 with ZnO have been registered by Raman spectroscopy.•Existence of ZnO nanoparticles surface optical phonon is evident.
Nanocrystaline samples of ZnO(Fe) were synthesized by traditional wet chemical method followed by calcinations. Samples were characterized by X-ray diffraction to determine composition of the samples (ZnO, ZnFe2O4 and Fe2O3) and the mean crystalline size (from 8 to 51 nm). In this paper we report the experimental spectra of Raman scattering (from 200 to 1600 cm−1) with surface optical phonons (SOP) in range of 500–550 cm−1. The phonon of registered phase’s exhibit effects connected to phase concentration, while the SOP phonon mode exhibit significant confinement effect.
