Efficient green emission from ZnMgS:Mn 2+ nanoparticles prepared by co-doping Mg 2+ and Mn 2+ ions into ZnS lattices has been observed. The synthesis is carried out in aqueous solution, followed by a post-annealing process, thus showing the features of less complexity, low cost, and easy incorporation of dopants. In comparison with the emission of ZnS:Mn 2+ nanoparticles, which is located generally around 590 nm, the photoluminescence of ZnMgS:Mn 2+ nanoparticles is blue-shifted by 14 nm in wavelength, leading to the enhanced green emission. The X-ray diffraction, electron spin resonance, and pressure dependent photoluminescence measurements suggest that the change of the crystal field caused by Mg 2+ ionic doping and the lower symmetry in the nanoparticles may account for the blue-shift of the photoluminescence. The ZnMgS:Mn 2+ nanoparticles with 1% Mn 2+ doping exhibit the strongest luminescence, which could potentially meet the requirements for the construction of green light emitting diodes.
