Luminescent and magnetic properties of Fe@C@YBO3:Eu3+ nanocomposites

• Fe@C@YBO3:Eu3+ nanocomposites with the core-shell structured were synthesized.
• Their structure, magnetic and luminescent properties are researched.
• The electronic transmission between the luminescent and magnetic properties of Fe@C@YBO3:Eu3+ composites is discussed.

In this work, Fe@C@YBO3:Eu3+ with magnetic and photolunminescent properties and core–shell structured bifunctional nanocomposites have been synthetized in a hydrothermal process. In the nanoparticles, the layer of amorphous carbon act as couplant, and this can conduct the excited electrons between magnetic part and luminescent part. Especially luminescent properties of Fe@C@YBO3:Eu3+ bifunctional nanocomposites under magnetic field was discussed. The nanocomposites obtained have been characterized by X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and transmission electron microscopy (TEM).
