“…The gel was obtained by aging at a proper temperature, and then it was calcined to remove the organic components. However, the method would produce narrow distribution of dysprosium oxide nanoparticles, but the precursors were expensive and also the process was time consuming [13,14]. Electrodeposition, a powerful and interesting process, can be applied in numerous fields [15].…”

The aim of this research was to introduce a new, facile and simple method for synthesis of Dy 2 O 3 nanostructures at room temperature. For the first time, galvanostatic electrodeposition was used to synthesize Dy 2 O 3 particles, and the influence of the current density on the structure and morphology of the product was studied. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Brunauer-Emmett-Teller (BET). The results show that the current density has little effect on the chemical composition but great effect on the structure and morphology of the samples. The average size of the particles decreases as the applied current density increases. The grain size of asprepared samples decreases from 500 to 70 nm when the current density increases from 0.5 to 6.0 mAÁcm -2 . To obtain oxide product, the as-prepared samples were heattreated at 1,000°C. The results show that the heat-treated samples have smaller particles. The XRD results show that the similar patterns are observed in the samples synthesized at different current densities, and the only difference from the JCPDS card is the ratio of peak intensities. With the increase in the current density, a decrease in the current efficiency is observed.
