In this work, copper oxide nanowires (CuO NWs) were synthesized on fuorine-doped tin oxide/glass substrates using the electrochemical technique followed by thermal oxidation in air atmosphere. In particular, we study the efect of the annealing time (4, 6, 8, 10 and 12 h) on CuO NWs properties. It was proved that the population density of CuO NWs decreased from 5.91 107 to 3.15 107 cm−2 as the annealing time increased from 4 to 12 h. The average diameter of CuO NWs increases from 69 to 114 nm for 4 to 10 h, and decreases to 100 nm for sample heated during 12 h. The EDS spectrum demonstrates that the CuO NWs are practically stoichiometric.
