abstract = "Nanocomposites derived from nano-scale inorganic/organic particles that are dispersed in a polymer matrix homogeneously have attracted considerable attention [1-3]. The diverse properties of numerous polymers to choose from are well documented, including both plastics and elastomers, which are the main two types of polymers. Organic/inorganic hybrid materials offer highly interesting and versatile applications when incorporated with a polymer. Among the inorganic/polymer nanocomposites, metal sulfides/polymer nanocomposites have been researched extensively due to their interesting optical, electrical and mechanical properties. Their excellent physical and chemical properties in various fields, such as catalysis, sensors, solar cells, photo detectors, light emitting diodes and laser communication, have made them very attractive and promising materials. Semiconductor particles immobilized in a polymer matrix with nano-scale grain size show different properties relative to the same material in bulk form because of quantum size effects. Many different synthetic approaches, like thermal evaporation, chemical bath deposition, chemical vapor deposition (CVD), laser ablation, hydrothermal, homogeneous precipitation in an organic matrix, sonochemical and sol–gel methods, have been employed for the synthesis of metal sulfide nanoparticles. In this work we investigate the structural and optical properties of polymer nanocomposites prepared by the incorporation of ZnS nanoparticles into the matrices of polymer poly (methyl methacrylate) (PMMA). The structural studies of the metal sulfides/polymer nanocomposites were carried out by Scanning electron microscopy (SEM), Raman spectroscopy and Far-infrared spectroscopy. The dielectric function of ZnS nanoparticles is modeled as a mixture of homogenous spherical inclusion in air, by the Maxwell-Garnet formula. In the analysis of the far-infrared reflection spectra, appearance of combined plasmon-LO phonon modes with high phonon damping are observed, which causes decreases of coupled plasmon-phonon frequencies.",
