Abstract

The paper deals with preparation of nanocrystalline zinc oxide doped with iron oxide obtained via calcination process. Mixture of iron and zinc hydroxides of various composition was used as precursor of nanopowders. The zinc ferrite samples were prepared by wet chemistry method - precipitation from the corresponding metals nitrates solutions using ammonia. The obtained hydroxides were filtered, dried and calcined at 300oC for 1 hour. Series of the samples containing 5 to 95 wt.% of Fe2O3 was obtained. The phase compositions of the samples were determined using XRD. Depending on the chemical composition the phases of hexagonal ZnO, and/or romboedric Fe2O3 and/or cubic ZnFe2O4 were identified. The mean crystallite size of ZnFe2O4 phase present in all the samples, determined using Scherrer’s formula, varied from 8 to 13 nm. The morphology of the samples was investigated using SEM and HRTEM. XPS measurements were conducted using Prevac UHV system. X-ray photoelectron spectra of all samples were analysed. Charging was reduced using neutralization cannon. Detailed spectroscopic and morphological analysis of the samples suggests core-shell model of the produced grains.
