Abstract

ZnSe nanoparticles are prepared by using chemical method in the presence of an optically transparent and semicrystalline polyvinyl alcohol (PVA) polymer matrix. The as-synthesized sample was characterized by using X-ray diffraction (XRD), Transmission electron microscope, UV-Vis absorption, photoluminescence spectroscopy and FT-IR spectroscopic techniques. The average crystallite size was found to be 6 nm from the XRD pattern. Optical absorption spectrum exhibited the bands which were corresponds to pure ZnSe. Photoluminescence spectrum exhibits the emission band at 431 nm with the excitation of 350 nm. FT-IR spectrum confirmed that PVA played the role of capping agent and coexisted in the lattice..
