Multifuctional Fe 3 O 4 @C/YVO 4 :Dy 3+ nanopowers: Preparation, luminescence and magnetic properties
Source abstract
Abstract
Abstract As-synthesized Fe 3 O 4 nanoparticles were encapsulated with carbon layers through a simple hydrothermal process. Fe 3 O 4 /C nanoparticles were coated with YVO 4 :Dy 3+ phosphors to form bifunctional Fe 3 O 4 @C@YVO 4 :Dy 3+ composites. Their structure, luminescence and magnetic properties were characterized by XRD, SEM, TEM, HRTEM, PL spectra and VSM. The experimental results indicated that the as-prepared bifunctional composites displayed well-defined core–shell structures. The ∼12 nm diameter YVO 4 :Dy 3+ shell exhibited tetragonal structure. Additionally, the composites exhibited a high saturation magnetization (13 emu/g) and excellent luminescence properties, indicating their promising potential as multifunctional biosensors for biomedical applications.
