中文摘要：

聚碳酸脂（PC）膜被高能重离子辐照后沿入射离子路径产生潜径迹，把带有潜径迹的膜经紫外光敏化后置于NaOH溶液中进行蚀刻，通过选择蚀刻条件，在PC膜内得到直径从100到500nm导通的核径迹孔．以带有核径迹孔的PC膜为模板，用电化学沉积法制备出不同直径的银纳米线．在特定的实验条件下（沉积电压25mV、电流密度1-2mA·cm^-2温度50℃和电解液为0．1mol·L^-1的AgNO3溶液），获得了沿[lll]方向择优取向生长的具有单晶结构的银纳米线．利用扫描电子显微镜（SEM）、X射线衍射（XRD）、透射电子显微镜（TEM）及选区电子衍射（SAED）等手段对银纳米线的形貌和晶体结构特征进行了表征．

英文摘要：

Polycarbonate （PC） membranes were irradiated with swift heavy ions and latent tracks were created along the ions＇trajectories. Nanopores, diameters between 100 and 500 nm, were obtained after illuminating the membranes with UV light and etching in NaOH solution. Silver nanowires were produced in the etched ion-track membranes by electrochemical deposition. The morphology and crystallinity of the silver nanowires were studied by means of scanning electron microscopy （SEM）, X-ray diffraction （XRD）, transmission electron microscopy （TEM）, and selected area electron diffraction （SAED）. Under certain conditions （deposition voltage 25 mV, current density 1-2 mA· cm^-2, temperature 50 ℃ electrolyte 0.1 mol-L-1 AgNO3）, single-crystalline silver nanowires with preferred orientation along the [lll] direction can be synthesized.
