- Abstract
Eu3+ and Dy3+ codoped Y2O3 (Y2O3:Eu3+, Dy3+) based bifunctional nanocomposites were fabricated by solid-state route. The magnetic component of the nanocomposites is Fe or Fe3O4. The composition and microstructure of the nanocomposites were studied. The results indicate that nanocomposites are mainly consisted of Y2O3:Eu3+, Dy3+ nanorods and Fe (or Fe3O4) nanoparticles. The length and diameter of the nanorods are in the size range of 500–1500 nm and 80–150 nm, respectively. The size of Fe or Fe3O4 nanoparticles is about 20 nm. A probable formation mechanism of nanocomposites has been analyzed. The fluorescence and magnetism of nanocomposites have been evaluated based on the influences of amount of raw materials.
