Synthesis and characteristics of multifunctional Fe3O4–SiO2–CdS magnetic-fluorescent nanocomposites

doi:10.1088/1674-1056/20/8/086101

Abstract A luminescent superparamagnetic nanocomposite with an Fe₃O₄—SiO₂—CdS structure is synthesised. 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 transmission electron microscopy (HRTEM), hysteresis loop, and photoluminescence (PL) spectrum, these nanocomposites exhibit superparamagnetic and photoluminescent properties.

Keywords: superparamagnetic nanoparticles CdS quantum dots
