摘要：
Polyvinyl-alcohol (PVA) has been used as the matrix to synthesize ZnS/PVA composite films by means of the Chemical method The as-obtained films were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), Atomic force microscopy (AFM), Ultraviolet-visible (UV-VIS) absorption, and photoluminescence (PL) spectra The results confirmed that the size of the as-synthesized ZnS nanoparticles depends on the amount of ZnCl(2) salt The photoluminescence and UV-VIS spectroscopy revealed that the ZnS/PVA films showed quantum confinement effect The primary FTIR spectra of ZnS/PVA nanocomposite in different PVA ZnCl(2) have been discussed The results indicate that the introduction of ZnS decreased the degree of crystallinity of PVA
