EQCM investigations of dye-functionalized nanocrystalline titanium dioxide electrode/solution interfaces: does luminescence report directly on interfacial electron transfer kinetics?

It was shown that reversible, potential-induced dye desorption occurs in both aqueous and nonaqueous environments at potentials close to the conduction band edge. Electrochemical quartz crystal microbalance experiments were carried out on dye-functionalized nanocrystalline titanium dioxide electrode/solution interfaces. Findings also showed decreases in the efficiencies of charge injection and increases in dye luminescence yield during potential changes.
