英文摘要	Wurtzite structure Ni and Co co-doped Zn0.97−xNi0.03CoxS (x = 0.01, 0.03 and 0.05) nanorods were successfully synthesized by a hydrothermal route with ethylenediamine. The effects of Co doping concentration on the crystal microstructure, morphology, optical and magnetic properties were systematically investigated by x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), energy dispersive spectrometry (EDS), UV–visible spectra (UV–VIS), photoluminescence (PL) and a vibrating sample magnetometer (VSM). The morphology of as-prepared samples is one-dimensional wurtzite rod-like with good dispersion. It is demonstrated that the Ni and Co co-doped ZnS nanorods lead to an increased visible light absorption, slightly increased band gap, and decreased PL intensity. Blue shift of the band gap occurs in doped Zn0.97−xNi0.03CoxS nanorods. PL spectra shows an obvious ultraviolet emission peak at 375 nm and a weaker side band at 730 nm, implying the excellent single-phase ZnS. Notably, two major blue emissions band around 497 nm and 576 nm are quenched sharply with the increase of Co doping concentration. The CIE chromaticity diagram results show that the prepared Zn0.97−xNi0.03CoxS samples exhibit excellent light-emitting ability. All samples possess ferromagnetic behavior at room temperature. The saturation magnetization of Zn0.97−xNi0.03CoxS nanorods with an appropriate amount of Co decreases obviously, reaching a minimum at 3% Co. © 2019, The Minerals, Metals & Materials Society.
