摘要：
Mn2+-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 degrees 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 ZnSMn2+ nanoparticles. Enhanced PL was observed from the surfactant-capped ZnSMn2+ nanoparticles. The PL spectra showed a broad blue emission band in the range 460445nm and a Mn2+-related yellow-orange emission band in the range 581583nm. Copyright (c) 2012 John Wiley & Sons, Ltd.
