Mn2+-doped ZnS (ZnS:Mn) nanoparticles were prepared using bis(2-ethylhexyl) sulfosuccinate (AOT) reversed micelle method. Luminescence at 583–589 nm were observed in the ZnS:Mn nanoparticles and are ascribed to Mn2+ ion in the nanoparticles due to energy transfer from ZnS. The luminescence was enhanced by capping with alkanethiol. Mono-and multilayered films with the alkanethiol-capped ZnS:Mn nanoparticles were fabricated on quartz substrates by layer-by-layer method using self-assembled monolayer (SAM) of 1,6-hexanedithiol. The polarization degrees of luminescence for the monolayered films were enhanced by preparation under applying magnetic field. The enhancements are probably caused by magnetic orientation of the ZnS:Mn nanoparticles on the quartz substrates.
