Abstract
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.
