Abstract
In this work, CdS nanoparticle with different sizes dispersed in polyvinyl alcohol (PVA) matrixes in the
form of (PVA/ CdS) nanocomposite were prepared. Results of transmission electron microscopy (TEM) and XRay
diffraction (XRD) indicates the well dispersed CdS uniform sphere nanoparticles with cubic phase have
been formed in PVA. The infrared spectral data confirmed that the -OH group used as a coordinated site to
aggregate the cadmium ions and different uniform sizes of CdS nanoparticles were formed at this site by
releasing of S-2 ions. The blue shift and optical band gap as a function of the particle sizes were studied form the
UV-Visible spectra. Dielectric properties were studied in the frequency range from (2.5 KHz-5 MHz) as a
function of temperature and the effect of particle sizes on the relaxation time were discussed.
