  • Mn-doped ZnS nanoparticles were prepared by the Sol-Gel process in this paper, and the influence of doping ion concentration on crystal structures and luminescent properties of ZnS: Mn nanoparticles was discussed. The structures of the samples were characterized by an X-ray diffractometer(XRD). The results show that the as-prepared ZnS: Mn nanoparticles belong to the cubic sphalerite structure. The parvafacies do not occur when Mn2+-doping concentration reaches 6% and the average particle sizes of nanoparticles decrease with the increase of doping concentration. Photoluminescence(PL) spectroscopy and fluorescence spectrum results show that the emission wavelengths of ZnS: Mn nanoparticles around 590 nm can be adjusted by changing the concentration of the ions. In addition, the influence of temperature on morphology and luminescent properties of nanoparticles was studied. The result observed from a high resolution transmission electron microscopy(HRTEM) shows that the average particle sizes of ZnS: Mn samples increase to about 20 nm after ageing for 1 h at the temperature of 50℃. The heating ageing is beneficial to Mn2+ fluorescence produced at 590 nm for ZnS:Mn nanoparticles.
