Luminescence and Spectral Characteristics of Zinc Sulfide Nanoparticles Doped with Eu 2+

method is proposed for the production of zinc sulfide nanoparticles with an average size of 6.0 ± 1.0 nm, doped with 2+ ions (molar ratio Eu : Zn ≈ 0.01%-0.19%), by simultaneous decomposition of diethyldithiocarbamate complexes of zinc(II) and europium(II) in high-boiling solvents. It was established that the position of the emission band at 645 nm for the obtained ZnS : Eu 2+ nanoparticles hardly depends at all on the europium content while the luminescence intensity is highest with a dopant content of 0.05%. It was shown that the emission band for the ZnS : Eu 2+ nanoparticles arises from Eu 2+ emission centers localized on the surface of the nanoparticles.
