Abstract
In the present work, we report a simple chemical precipitation method to synthesize precursors of different levels of Cu(2+) ions doped crystalline zinc oxide (ZnO) nanoparticles in the presence of capping agents namely cetyltrimethyl ammonium bromide (CTAB) and sodium hexametaphosphate (SHMP). Thermal analysis result suggests that 300°C could be the optimum level of annealing for the harvest of pure phase of ZnO from the as prepared particles. The structural, optical and chemical features of undoped and surfactants assisted ZnO: Cu(2+) nanoparticles were studied by X-ray powder diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-Visible (UV-Vis) absorption spectroscopy and photoluminescence (PL) measurements. Among the two surfactants used SHMP is an effective one in controlling the size and morphology of the particles.
