文摘
- •
Homogeneous size distribution of magnetic-upconversion core@shell structured nanoparticles (NPs) were synthesized.
- •
The core@shell nanostructures were obtained by seed-growth method.
- •
The oleic acid coated Fe3O4 NPs were used as seeds and cores.
- •
The magnetic-upconversion NPs emitted red luminescence under a 980 nm laser.
- •
Synthesized magnetic-upconversion NPs were phase transferred using ligand exchange process.
