Abstract
A rapid microwave-assisted synthesis and detailed characterization of a bifunctional nanocomposite composed of a magnetic core, Fe3O4, and a semiconductor shell, CdSe, are reported. Magnetite Fe3O4 nanoparticles are synthesized and used as seeds for the heterogeneous nucleation and growth of the CdSe nanoshells. The optical properties of the nanocomposites are assessed by UV–Vis and photoluminescence measurements. In addition, the crystalline phase and size distribution of the nanocrystals are determined by XRD and TEM, respectively. The results indicate that the as-prepared nanocomposites are nearly monodisperse with an average size of 10 nm and a quantum yield of 13 %. The synthesized nanocomposites clearly provide both magnetic and luminescent properties which could be useful for simultaneous detection and separation possibly in biomedical applications.
