Poly( o ‐methyl‐acrylamideyl‐benzoic acid)‐ZnS (P( o ‐MAABA)‐ZnS) nanocomposites have been prepared and characterized. The resultant P( o ‐MAABA)‐ZnS nanocomposites in solution show two emissions in the purple‐light area (370 nm) and in the blue‐light area (425 nm), which are assigned to the polymer and ZnS nanoparticles, respectively. The coordination between the polymer and Zn 2+ and the surface chemical composition has been studied by Infrared spectroscopy and X‐ray photoelectron spectroscopy (XPS). The particle size of ZnS nanoparticles was homogeneous and the average size was 3.8 nm, which were characterized by UV absorption spectrum and X‐ray Diffraction. The P( o ‐MAABA)‐ZnS composites displays good film formability and the films also show two emissions in 370 and 425 nm. After doped with Tb 3+ , there was effective energy transfer from ZnS nanoparticles to Tb 3+ . © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
