AbstractMn-doped ZnO-ZnS complex nanocrystals were fabricated through coating of dodecanethiol on Mn-doped ZnO nanocrystals. The relationship between the component of white light emission and the coordination environments of Mn-dopants were experimentally investigated. It was shown that Mn ions mainly formed Mn3+O6 octahedra in as prepared Mn-doped ZnO, while the Mn3+ ions on the surface of ZnO transferred into Mn2+ ions at the interface between ZnO and ZnS after dodecanethiol coating. The Mn2+S4 tetrahedron density and the orange emission intensity increased upon enhancing the dodecanethiol content. These results provide an alternative way to optimize the white emission spectrum from nanocrystals of Mn-doped ZnS-ZnO complex structures through modulation of the coordination environment of Mn ions.
