ld nanowires with diameters (d) between 45 nmand 200 nmand with length/diameter ratio of 700 were prepared in ion-track templates with electrodeposition method. The morphology and crystal structure of the ld nanowires were studied by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The 200 nm (d) ld nanowires preferred orientation along the [100] direction were formed at the deposition voltage of 1.5 V (without reference electrode). The optical properties of ld nanowire arrays embedded in ion-track templates were studied by UV-Vis spectrophotometer. There was a strong absorption peak at 539 nm for 45 nm (d) ld nanowire arrays. With the diameter of ld nanowires increasing, the absorption peak shifted to the longer wavelength. At last, the result was discussed combined with surface plasmon resonance of ld nanoparticles.
