  • Title: Synthesis, effect of capping agents and optical properties of manganese-doped zinc sulphide nanoparticles.
    Author: Murugadoss G, Ramasamy V.
    Journal: Luminescence; 2013; 28(1):69-75. PubMed ID: 22730304.
    Abstract:
    Mn(2+)-doped ZnS nanoparticles have been successfully synthesized by a chemical precipitation method, using non-ionic surfactants such as PMMA and PEG. The particles were prepared in an air atmosphere at 80 °C. X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-visible and photoluminescence (PL) studies were used to investigate the effect of the capping agent on the size, morphology and optical properties of the ZnS-Mn(2+) nanoparticles. Enhanced PL was observed from the surfactant-capped ZnS-Mn(2+) nanoparticles. The PL spectra showed a broad blue emission band in the range 460-445 nm and a Mn(2+)-related yellow-orange emission band in the range 581-583 nm.
