Abstract

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.
