中文摘要: 具有室温铁磁性能的Cr掺杂CdS纳米棒用简单的溶剂热法被成功地合成。X-射线衍射(XRD)分析表明产物为六方相CdS。 透射电镜(TEM)分析表明,不同铬含量的CdS均为纳米棒,CdS纳米棒长为100-350 nm,平均直径为20-30 nm,几乎与掺入铬的质量无关。 能量色散谱(EDS)测试表明,合成产物由S、Cd和Cr组成。振动样品磁强计(VSM)表明,Cr掺杂CdS纳米棒在室温下具有铁磁性,而没有Cr掺杂CdS纳米棒具有弱铁磁性。Cr掺杂CdS纳米棒(Cr = 4.17 at%,7.31 at%)的饱和磁化强度Ms分别约为3.907和8.798(10-3 emu/g),Hc的矫顽力约为96.21和 137.15 Oe。 CdS纳米棒室温铁磁性能的产生与CdS晶格中Cd原子被Cr的取代有着密切关系。

Abstract:Cr-doped CdS nanorods with room temperature ferromagnetism were successfully synthesized by simple solvothermal method. X-ray diffraction (XRD) analysis showed that the product was hexagonal CdS. Transmission electron microscopy (TEM) analysis showed that CdS with different chromium contents were nanorods, the length of CdS nanorods was100-350 nm, and the average diameter was 20-30 nm, which was almost independent of the quality of chromium doped. Energy dispersive spectroscopy (EDS) measurements demonstrated that the synthesized product was composed of S, Cd and Cr. The vibrating sample magnetometer (VSM) demonstrated that Cr-doped CdS nanorods exhibitted ferromagnetism at room temperature, while non Cr-doped CdS nanorods exhibitted weak ferromagnetism. The saturation magnetization Ms of Cr-doped CdS nanorods (Cr = 4.17at%, 7.31at%) was about 3.907 and 8.798 (10-3emu/g) respectively, and the coercivity of Hc was about 96.21 and 137.15 Oe.? The room temperature ferromagnetic properties of CdS nanorods were closely related to the substitution of Cd atoms by Cr in the CdS lattice.
