Tailoring the structural, optical and multiferroic properties of low temperature synthesized cobalt ferrite nanomaterials, by citrate precursor method

Thermally induced oxygen related defects in eco-friendly ZnFe2O4 nanoparticles for enhanced wastewater treatment efficiencies

“…All corresponding peaks of ferrite structure were clearly visible in all ZFO samples with no evidence of any impurity peaks. The spectrum consists of five main obvious peaks at v 1 = 450 cm -1 , v 2 = 547 cm -1 , v 3 = 1612 cm -1 and v 4 = 2414 cm -1 and v 5 =3400 cm -1 which matches well with ferrite structures (Bhushan Das et al, 2021). The peaks v 1 and v 2 may be related to Fe-O and Zn-O stretching vibrations, which represent the metal bonding at tetrahedral site of the spinel ferrite structure.…”
