The purpose of this work was to study optical properties of nanosized powders of ZnO doped with Fe2O3, MnO and CoO. Nanocrystaline samples were synthesized by wet chemical method. Samples were characterized by X-ray diffraction to determine composition of the samples. The mean crystalline size varied from 8-52 nm for ZnO doped with Fe2O3, between 9-100 nm for ZnO doped with MnO and between 14-156 nm for ZnO doped with CoO.

    In this paper we report the experimental spectra of micro-Raman measurements, at different laser powers. With increases of laser power, the peaks shift to lower frequencies and broaden. In all samples Raman peak at 436 cm-1 is clearly visible. This peak is typical for undoped ZnO nanoparticles [1].

    For the samples of ZnO doped with Fe2O3 the Raman spectrum shows the band at ~ 642 cm-1. The presence of this band is typical for Fe doped ZnO nanoparticles [1]. In these samples, especially in case of high doping level, bands from various crystal structures are identified (Fe2O3, ZnFe2O4) from about 514 to 660 cm-1.

    For the samples of ZnO doped with MnO Raman peak at ~ 660 cm-1 is clearly visible.     This peak is typical for spinel structure. In these samples especially in case of high doping level, bands from various crystal structures are identified (ZnMnO3, Mn3O4) at about 315 and 525 cm-1.

    For the samples of ZnO doped with CoO the Raman spectrum shows the band at ~ 691 cm-1. The presence of this band is typical for Co3O4. We also observed bands at ~ 194, 482, 521 and 618 cm-1. These bands are typical for Co3O4, too.
