摘要

A stable and narrowly distributed dispersion of Mn-doped ZnS (sphalerite) nanoparticles with an average diameter of 1-2 nm, has been synthesized via chemical precipitation without using any surfactant. The surface of the particles has been functionalized with acrylic acid for compatibilization with polymethylmetacrylate (PMMA). A thorough morphological and optical characterization is proposed. A high nonlinearity in the response of the material is evidenced, with the maximum of luminescence obtained with 5%mol Mn doping.
