Hybridization of dissimilar building materials into highly-organized structure can tailor the functionality of each component. In particular, the coupling among fluorescent dyes, quantum dots (QDs), and metal nanoparticles (NPs) can play a critical role in optoelectronic and bio systems because their inter-combined effects can exhibit novel optical properties. As those coupling effects strongly depend on their mutual distance and position in a nanometer scale, we envisioned that diblock copolymer micelles can provide a modality for the arrangement of dissimilar functionalities from the following observations; (1) a single-layered film of copolymer micelles can be easily fabricated by spin-coating, (2) some dye molecules are found to be incorporated solely into micellar core, and (3) QDs can be positioned at the peripheral region of micelles in their single-layered film. These unique properties of micelles were applied to engineer the mutual interaction among dyes, QDs, and metal NPs. |
