Electrochemically modulated FRET from assemblies of quantum dots and transition metal complexes.
(in collaboration with Jacek Jasieniak - CSIRO Division of Molecular and Health Technologies)I am very excited by this project. The possibility of controlling quantum dots emission electrochemically has enormous implications for sensor and light emitting device technologies.
The figure shows one of many possible configurations: Diazonium chemistry will be used to form an amine modified electrode surface – an ideally stable platform on which to co-immobilise highly luminescent ruthenium complexes and core shell quantum dots. Electron transfer to the electrode generates a ruthenium excited state initiating Förster Resonance Energy Transfer (FRET) to the quantum dot, which then emits light at its characteristic wavelength.
