Preparation and properties of multifunctional Fe@C@Y2O3:Eu3+ nanocomposites

► Multifunctional Fe/Fe O @Y O : Eu nanocomposites were prepared by a solvothermal method. ► Their structure, magnetic and luminescent properties were characterized by XRD, SEM, TEM, excitation and emission spectra and vibration sample magnetometry (VSM). ► It is shown that the nanocomposites exhibi...

description: ► Multifunctional Fe/Fe O @Y O : Eu nanocomposites were prepared by a solvothermal method. ► Their structure, magnetic and luminescent properties were characterized by XRD, SEM, TEM, excitation and emission spectra and vibration sample magnetometry (VSM). ► It is shown that the nanocomposites exhibit high saturation magnetization and strong red emission under UV-light. Multifunctional Fe@C@Y O :Eu nanocomposites were prepared by the solvo thermal method, and their structure, magnetic and luminescent properties were characterized by X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and scanning electron microscope (SEM). Results show that the nanocomposites are spherical with a mean diameter of 700 nm and there are high special saturation magnetization (47.4 emu/g) and strong red emission under UV-light. Even dispersed in water solution, the nanocomposites also exhibit a strong red emission under ultraviolet light radiation, and it could be manipulated using an external magnet. Thus it looks promising for application in biomedicine field, especially in drug targeting and fluorescence label. And we also discussed the effect of the electron transfer process between the Fe magnetic core and Y O :Eu shell.
