Tuning the optical and magnetic properties of Mn3O4 quantum dots by annealing process
Mn 3 O 4 quantum dots (QDs) are synthesized at room temperature, and the resulting samples are annealed at the temperature of 523 K and 773 K. The crystallinity, average particle size, and lattice parameters of the prepared manganese oxide QDs are analyzed using X-ray crystal diffraction (XRD) studi...

quantum dots (QDs) are synthesized at room temperature, and the resulting samples are annealed at the temperature of 523 K and 773 K. The crystallinity, average particle size, and lattice parameters of the prepared manganese oxide QDs are analyzed using X-ray crystal diffraction (XRD) studies. Furthermore, X-ray photoelectron spectroscopy (XPS) is used to investigate the elements present on the surface of nanomaterials, the oxidation state, and the type of functional groups attached to the surface of QDs. The optical and magnetic properties of the produced QDs have also been studied with UV–Visible absorption spectra and vibrating sample magnetometer (VSM), respectively. Single-phase Mn
