摘　　要：Ag_2S nanoparticle nanowires were prepared in a porous anodic aluminum oxide template by a simple paired cell method,and were characterized by XRD,FESEM,HRTEM and EDS.The results showed that the as-prepared nanowires were composed of monoclinic Ag_2S nanoparticles.The nanowire diameters ranged from 165 to 270 nm,and Ag_2S nanoparticles were nearly spherical with diameters of 40 to 60 nm.The paired cell method is simple,low cost and easy to control for the fabrication of high density and high aspect ratio Ag_2S nanoparticle nanowires.A formation mechanism for the nanoparticle nanowires was suggested.Ag2S nanoparticle nanowires were prepared in a porous anodic aluminum oxide template by a simple paired cell method, and were characterized by XRD, FESEM, HRTEM and EDS.
