Abstract
In this report, Dy2O3 (dysprosia) nanoparticles were prepared by using the combustion method. The innovative aspect of this method is preparation of dysprosium oxide nanoparticles without applying calcination temperature. To study the effect of the heating and annealing on the structure of dysprosia, three different calcination temperatures, 450, 550, and 650 °C were applied on the no-calcined sample. TEM and X-ray diffraction XRD were used for characterization of the samples. Diffraction pattern of samples were achieved by selected area electron diffraction (SAED). XRD patterns show the desired cubic structure for all samples. The results of crystallite sizes, estimated by the broadening of XRD peaks, showed the size of crystallites in the range of 24–28 nm. TEM showed the average size of the particles in the range of 28–41 nm.
