Abstract |
|
|
| In present study sol-gel autocombustion techniques were used to create Dysprosium (Dy3+) doped Copper ferrites. Characterization of these produced compounds was done with XRD, SEM, FTIR, VSM, TG-DTA, and TEM. The TGA shows weight loss is caused by the autocatalytic oxidation reduction reactions of nitrates. Dy3+doped inCuxFe2−xO4 (x=0.00, 0.025, 0.05, 0.075, 0.1, 0.125 and 0.15) exhibits a shape resembling fibrous reticulated grid. When Dy3+ concentration rises, the average grain size also rises. The XRD analysis of copper ferrite doped with Dy3+ exhibits a cubic spinel phase. The TEM investigation revealed that the particle size was between 30 to 40 nm. The FT-IR spectra displayed two prominent absorption bands at 540 cm−1, which are indicative of the metals intrinsic stretching vibrations at the tetrahedral site, and lowest band detected at 424 cm−1 corresponds to the octahedral site, while the co-tetrahedral site.
