Abstract :
Manganese-doped zinc sulfide nanocrystalline powders have been synthesized from zinc-manganese acetate and sodium sulfide, in methanol containing methacrylic acid as additive. Precipitation was performed at low temperature, using the reagent simultaneous addition technique. All samples were characterized by photoluminescence spectroscopy electron microscopy and X-ray diffraction. A correlation between the preparation conditions and optical and morphological characteristics of ZnS:Mn2+ powders was established.
