Abstract: New synthesis precipitation technique to prepare nanoparticles of Mn-doped zinc sulphide ZnS:Mn2+ have been attempted. Various capping agents have been used to control the morphostructural properties of ZnS:Mn2+ particles. Infrared absorption spectroscopy (FT-IR), photoluminescence spectroscopy (PL), scanning (SEM) and transmission electron microscopy (TEM) were used to characterise the powder samples. Strong luminescent ZnS:Mn2+ nanocrystalline powders could be precipitated at room temperature, from sodium sulphide and zinc-manganese acetate solutions, using the reagent simultaneous addition technique-SimAdd and methacrylic acid or sodium dodecyl sulphate as passivating agent.
Keywords: ZnS nanoparticles, Mn-doped nanoparticles, photoluminescence. |
