Besides of the quantum effect from quantum dots and their fantastic optoelectronic properties, the key issues of metal/semiconductor binary cooperative nano-system is the coherence between near field enhancement from localized SPR effect and exciton bohr radius related quantum confinement effect at the nanoscale. To achieve flexible coupling between Plasmon and exciton and then enhanced optoelectronic applications, the synergistic tailoring of shape, size, composition, crystallization, hetero-interface and the distance between two nanoscopic components comparable to the characteristic length of plasmon/exciton interactions are key materials issues. By controlling soft acid-base coordination reactions between molecular complexes and colloidal nanostructures, we showed that: i) proposed the new synthesis method, namely different kinds of phosphine initialized cation exchange reactions, to precisely synthesize metal/semiconductor hetero-nanostructures and doped semiconductor nanostructures; ii) realized synergistic tailoring on morphologies, compositions and hetero-interfaces of many kinds of metal@monocrystalline semiconductor core/shell nanocrystals and the exploration of their photochemical energy conversion applications; iii) developed the new cation exchange strategy to realize the successive control of substitutional heterovalent doping, surface/interface control, doped luminescence and p-/n-type electronic impurities in semiconductor nanostructures, and explored their photoelectric conversion applications.
