Abstract

Yttrium- and indium-doped zinc-ferrite nanoparticles (Zn1-xMxFe2O4 for 0≤x≤0.6) were prepared using a coprecipitation method. The nanoparticles were charactarized by conventional powder X-ray diffraction, energy dispersive X-ray spectrometry, transmission electron microscopy, Raman and Mössbauer spectroscopy. The influence of doping level on the structure of the as-synthesized nanoparticles were investigated. It was found that Y-doped ZnFe2O4 nanoparticles, with single spinel phase and size of few nanometers, are formed in a whole range of yttrium addition. On the other hand, In-doped ZnFe2O4 nanoparticles can be formed for all x investigated, but only the samples Zn1-xInxFe2O4 with x£0.15 are single phase spinel (for x³0.20 a second phase is formed).
