CdSe nanofiber and nanohorn structures on ITO substrates fabricated by electrochemical deposition

Self assembled 3-D CdSe structures have been successfully electrodeposited from aqueous solutions. Proposed method allows a control of self-assembled nanostructures formation with a different morphology by varying the composition of the electrolyte in electrochemical bath. The two types of 3-D nanostructures: CdSe nanofibers (ø 30 nm, length of 1–2 μm) and Se core–CdSe shell nanohorns (ø 200 nm, length of 600 nm) were fabricated and investigated. The possible mechanism of electrochemical formation of CdSe nanofibers and nanohorns has been proposed.
