Multifunctional nanocomposites with magnetic and luminescent properties were synthesized by a combination process of hydrothermal and sol–gel techniques. In this process, multiwalled carbon nanotubes (MWNTs) were decorated with Fe3O4 beads, forming Fe3O4/MWNTs nanoparticles. Then, the surface of Fe3O4/MWNTs samples was functionalized by the deposition of YVO4:Eu3+ phosphors. X-ray diffraction, field emission scanning electron microscopy, energy disperse X-ray spectroscopy, transmission electron microscopy, and photoluminescence spectra were used to characterize the samples. The results reveal that the nanocomposites exhibit high magnetization (38 emu/g) and show the characteristic emission of Eu3+ (5D0 → 7F1–4). This functionalized nanocomposite is expected to find potential applications in biomedical areas.
