Bifunctional magnetic-luminescent nanocomposites:: Y2O3/Tb nanorods on the surface of iron oxide/silica core-shell nanostructures

Bifunctional magnetic -luminescent Fe3O4@SiO2/Y2O3:Tb nanocomposite was obtained by assembling Y2O3: Tb nanorods onto the surface of Fe3O4@SiO2 core-shell nanostructures. Transmission electron microscopy, energy dispersive X-rays (EDX), room temperature photoluminescence spectra, and superconducting quantum interference device magnetometry were used to investigate the morphology and properties of the nanocomposite. The results showed that the nanocomposite displayed a strong green emission and superparamagnetic behavior at room temperature; therefore, the nanocomposite is expected to find many potential applications in biomedical fields.
