Abstract

Abstract : Hexagonal CdS and Fe‐doped CdS nanorods were synthesised by a facile hydrothermal method and characterised by X‐ray diffraction, energy dispersive X‐ray spectroscopy, UV–vis absorption, photoluminescence, and X‐ray photoelectron spectroscopy. The magnetic properties of undoped and Fe‐doped CdS nanorods were investigated at room temperature. The experimental results demonstrate that the ferromagnetism of the Fe‐doped CdS nanorods differs from that of the undoped CdS nanorods. The remanence magnetisation ( M r ) and the coercive field ( H c ) of the Fe‐doped CdS nanorods were 4.9 × 10 −3 emu/g and 270.6 Oe, respectively, while photoluminescence properties were not influenced by doping. First‐principle calculations show that the ferromagnetism in Fe‐doped CdS nanocrystal arose not only from the Fe dopants but also from the Cd vacancies, although the main contribution was due to the Fe dopants.
