摘要：

ZnS:Mn2+ nanowires (NWs)/SiO2 nanocomposites were successfully synthesized by Stober method. The results showed that Mn2+ ions were incorporated into the ZnS lattice and the average diameter of ZnS:Mn2+ NWs and ZnS:Mn2+ NWs/SiO2 nanocomposites was 8.8 and 25 nm, respectively. The photoluminescence (PL) intensity of the yellow-orange emission coming from the Mn2+ ions (T-4(1)-(6)A(1) transition) for both ZnS:Mn2+ NWs and ZnS:Mn2+ NWs/SiO2 nanocomposites was increased as the Mn2+ doped ratio increased, and showed a maximum when the concentration of the Mn2+ ions kept at 3%. After embedding ZnS:Mn2+ NWs within SiO2 matrix, the PL intensity of the yellow-orange emission is higher than that of ZnS:Mn2+ NWs, indicating the effective surface passivation by SiO2.
