Abstract
CuI nanowires with uniform diameter were successfully fabricated by vacuum melting and gas pressure injection via AAO template. The nanowires exhibit the characteristics of continuous and compact at the gas pressure of 5MPa, and the gas pressure can be reduced to 1MPa with a CuI pre-processed AAO template, The results of XRD and EDS indicate that the nanowires belong to the zinc-blende structure and the amount of copper is more than that of iodide in the sample. The CuI nanowires present a weak near-band emission with a fast decay time and a strong defect emission with a slow decay time, and the intensity of fast emission component can be improved by iodine doping.
