通过化学镀镍纳米粒子在CdS纳米线上制备了一维CdS-Ni半导体磁性纳米复合材料。预制的 CdS 纳米线，直径约为45 nm，长度可达几十μm，通过在140°C的乙二醇中肼诱导氯化镍还原而被磁性功能化。结果发现，镍纳米粒子的直径约为。 80 nm 锚定在纳米线上，无需任何表面预处理。此外，检测并证实了转化过程，这有利于镍纳米粒子在 CdS 纳米线上的非外延生长。通过XRD、TEM、HR-TEM和EDS技术对所制备的产物进行了详细表征。磁性测量表明，纳米复合材料在室温下表现出铁磁性。（© Wiley-VCH Verlag GmbH & Co.

Preparation of 1D CdS-Ni semiconductor-magnetic nanocomposites was achieved by means of electroless plating of nickel nanoparticles on CdS nanowires. Preformed CdS nanowires with a diameter of ca. 45 nm, a length up to several tens of μm were magnetically functionalised by the hydrazine-induced reduction of nickel chloride in ethylene glycol at 140 °C. It was found that nickel nanoparticles with a diameter of ca. 80 nm anchored on the nanowires without any surface pretreatment. Furthermore, a conversion process was detected and confirmed, something which is favourable for the nonepitaxial growth of Ni nanoparticles on CdS nanowires. The products prepared thereof were characterised in detail by XRD, TEM, HR-TEM and EDS techniques. Magnetic property measurements show that the nanocomposites display ferromagnetic properties at room temperature.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
