Electrodeposition of Quantum-confined Metal/semiconductor Nanocomposites
Electrodeposition as an approach to quantum confinement is the idea behind the work on nanocomposite films of Cu and Cu₂O reported here. the phase of the film electrodeposited from an alkaline aqueous solution of copper(II) lactate depends on the cathodic current density used, varying from pure Cu₂O (a p-type semiconductor) to 98 mol-% Cu, the color of the film changing correspondingly; the electrode potential oscilates spontaneously at fixed current density. It is shown that the Cu₂O crystallites exhibit the optical properties of quantum dots.
