In the present report formation of nano-sized PbS in MA/octene-1 copolymer matrix at 80 degrees C temperature is being reported. A size and distribution of particles were observed in AFM results and the images are correlated with the results on X-ray diffraction measurements. The structure and phase of the PbS nanoparticles were characterized by X-ray diffraction (XRD). XRD studies reveal that as-synthesized PbS nanoparticles are in single phase cubic structure and the grain size have been calculated 10-15 nm from XRD results. The size distribution was further supported by UV/Vis absorption and photoluminescence (PL) spectroscopy of the colloid nanoparticles. The obtained nanocomposites show an emission peak at 418 nm.
