Abstract
Quantum dots are modified with varying amounts of (a) a redox-active moiety effective to perform charge transfer quenching, and (b) a fluorescent dye effective to perform fluorescence resonance energy transfer (FRET), so that the modified quantum dots have a plurality of photophysical properties. The FRET and charge transfer pathways operate independently, providing for two channels of control for varying luminescence of quantum dots having the same innate properties.
