摘要
Core/shell Fe3O4-Au/silica nanoparticles with controllable fluorescein doped into nanoporous silica shells are synthesized. The quantum yield of fluorescein significantly increases through a synthetic electromagnetic field coupling of the dumbbell-like Fe3O4-Au cores. Theoretical simulation further proves that the anomalously plasmonic oscillation of Fe3O4-Au nanoparticles is a dominant contributor to the fluorescence enhancement.
