- Abstract
Manganese-doped zinc sulphide nanocrystalline powders have been synthesized from zinc-manganese acetate and sodium sulphide, in aqueous solution containing methacrylic acid. Precipitation was performed at low temperature, using the sequential reagent addition technique. Different Mn2+ concentrations have been used to control the optical properties of ZnS:Mn2+ nanoparticles. All samples were characterized by thermal analysis (TGA), infrared absorption spectroscopy (FT-IR), photoluminescence spectroscopy (PL), scanning (SEM) and transmission electron microscopy (TEM). A correlation between the preparation conditions and optical and morphological characteristics of ZnS:Mn2+ powders was established.
