The fluorescence resonance energy transfer (FRET) between fluorophores can play a critical role in optoelectronic and bio systems because their luminescent properties can be controlled by regulating mutual distance and position between energy-absorbing donors and energy-taking acceptors in a nanometer scale. In this study, we demonstrate selective encapsulation of multiple fluorescent dyes, which are capable of the FRET, in the cores of polystyrene-b-poly(4-vinyl pyridine) diblock copolymer micelles. Since the locations of three different fluorescent dyes were confined in the nanometer sized core of micelles, their mutual distance and position in a thin film were accurately controlled by employing different encapsulating protocols, which resulted in the controlled light emission of multiple fluorescent dyes by the FRET. |
