Coated with a silica shell, Fe3O4 nanoparticles and CdS quantum dots （QDs） are successfully assembled together. Analysed from the test results of X-ray diffraction （XRD）, transmission electron microscopy （TEM）, high resolution transimission electron microscopy （HRTEM）, hysteresis loop, and photoluminescence （PL） spectrum, these nanocomposites exhibit superparamagnetic and photoluminescent properties.展开更多
