摘要
We report the structural and magnetic properties of the CdS nanoparticles co-doped with Ni and Cu; 3% Ni, Cu co-doped CdS nanoparticles were synthesized by using wet chemical synthesis process. From high-resolution transmission electron microscopy (HR-TEM), it is found that the average diameter of the Ni, Cu co-doped CdS nanoparticles is about 5 nm. X-ray diffraction (XRD) studies show the zinc blende (cubic) structure of Ni, Cu co-doped CdS nanoparticles. Energy dispersive spectroscopy (EDS) confirms the elemental composition of the doped sample. Room temperature magnetic studies are made by the analysis of M-H curves, obtained using superconducting quantum interference device (SQUID). The magnetic behavior has been shown by CdS nanoparticles doped with 3% nickel as well as CdS nanoparticles co-doped with 3% Ni and Cu.
