In this study, the preparation of a new kind of magnetic and luminescent Fe₃O₄/CdTe nanocomposites was demonstrated. Superparamagnetic Fe₃O₄ nanoparticles were first synthesized by hydrothermal coprecipitation of ferric and ferrous ions, followed by the modification of their surfaces with tetramethylammonium hydroxide (TMAOH) and the chemical activation with aspartic acid. The surface-modified Fe₃O₄ nanoparticles were then covalently coated with CdTe quantum dots (QDs), which were modified with mercaptoacetic acid (MPA), to form the Fe₃O₄/CdTe magnetic and luminescent nanocomposites through the coordination of the amino groups on the surfaces of Fe₃O₄ and the carboxyl groups on CdTe QDs. The structure and properties of as-synthesized nanocomposites were characterized. It was indicated that the nanocomposites possessed structure with an average diameter of 40-50 nm, yellow-green emission feature and room temperature ferro-magnetism. Both the fluorescence and UV-vis absorption spectra of the nanocomposites showed a blue shift comparing with those of CdTe QDs. The mechanism of the blue shift was presented. The nanocomposites retained the ferromagnetic property with a saturation magnetization of 8.9 emu/g.
