摘要

摘要: 采用电沉积法成功制备Cu 准一维纳米线及Cu/ Al₂O₃ 纳米复合材料。采用SEM、TEM、XRD 分析技术对纳米线及其组装体系进行了形貌、相结构的观察和表征。紫外2可见光吸收光谱测试表明: Cu/ Al₂O₃ 组装体吸收光谱上仅呈现出一个吸收带边, 无等离子共振吸收峰, 且吸收边相对于阳极氧化铝模板发生了红移。红移主要归结为雷利散射中心的增加, 使消光现象增强所致。

Abstract: One-dimensional Cu nanowire and Cu/ Al₂O₃ composite materials were prepared successfully by elect rodeposition. The phase microst ructure and morphology were characterized by SEM , TEM and XRD. There exist oneabsorption belt and no plasm resonance absorption peak in analysis of ult raviolet-visible absorption spect rum. Theabsorption border shif t to the inf rared direction in cont rast to the anodic alumina template is due to the increasing ofdispersion center.
