    摘要:

    利用多孔阳极氧化铝模板辅助法,在Co电解液和CdSe电解液的双槽体系中用直流电沉积法交替沉积合成一维多段Co-CdSe金属-半导体异质结纳米线。异质结纳米线的形貌、结构、磁学及光学特性分别用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、振动样品磁强计(VSM)、紫外可见分光光度计(UV-Vis)以及光致发光光谱仪(PL)进行表征。结果表明,Co-CdSe异质结纳米线分层明显,且同时以面心立方结构存在。Co-CdSe异质结纳米线拥有与单质金属Co纳米线相同的磁矫顽力,同时,异质结纳米线也表现优异的光学性能。

    Abstract:

    One-dimensional multi-segment Co-CdSe metal-semiconductor heterojunction nanowires were alternately deposited by direct current electrodeposition in a two-cell system of Co electrolyte and CdSe electrolyte using porous anodized aluminum template assisted method. The morphology, structure, magnetic and optical properties of the heterojunction nanowires were characterized by scanning electron microscopy (SEM), X-ray diffractometry (XRD), vibrating sample magnetometer (VSM), UV-visible spectrophotometer (UV-Vis) and photoluminescence spectroscopy (PL). The results show that the Co-CdSe heterojunction nanowires are well layered and exist in a face-centered cubic structure. The Co-CdSe heterojunction nanowires have the same magnetic coercivity as the elemental metal Co nanowires, and simultaneously, the heterojunction nanowires exhibit the excellent optical properties.
