Abstract

In Raman scattering spectra of nanocrystaline samples ZnO(Co), surface optical phonons (SOP) were observed in the range of 496 – 546 cm-1. With X - ray diffraction measurements were determined the phase composition of the samples (ZnO, Co3O4) and the mean crystalline size (14-156 nm) where 53% of samples have mean crystalline size between 14 and 30 nm, 24% between 40 and 60nm, 17% larger than 100 nm and 6% have 80 nm. From this measurement becomes obvious the change of position of SOP modes with crystalline size and change of intensity of SOP modes with change of CoO concentration of doping element..
