Physics, KGIET, Amravati, India 1 Abstract: Poly(ethylene oxide) (PEO) complexed with Cadmium sulfide (CdS) are prepared by a solution cast technique. Several experimental techniques such as XRD, SEM, FTIR, DSC, PL and Raman spectroscopy are employed to characterize the sample. The powder X-ray diffraction (XRD) result indicates that the nanoparticles are crystallized in cubic phase. The UV-visible absorption, Differential scanning calorimetry, Photoluminescence and Raman spectra of the sample are recorded and discussed briefly. Keywords: CdS/PEO thin film, XRD, SEM, FTIR, DSC, UV, PL, Raman Spectroscopy I. INTRODUCTION Composites of inorganic particles with polymers is an interesting research subject because of the important potential applications in photocatalytic degradation of polymers, the production of controlled release products such as pesticides and drugs, and in the fields of adhesives, textiles, optics and electronics. The polymer nanocomposites has been successfully used for various stable inorganic colloids free from aggregation, such as titanium oxide, zinc oxide, magnetic and metal nanoparticles [1, 2]. Polyͼethylene oxideͽ has known to exhibit the property to solvate high concentration of ionic salts. The complexation of ionic salts with PEO has been the subject of active interest in polymer electrolytes, where the weak columbic interaction between the cations and ether oxygen being the major to facilitate ion pair separation. Over the last three decades, many polymeric electrolytes are based on various salts dissolved in polyethers, particularly PEO have been widely investigated because of their applications in high performance batteries. II. EXPERIMENTAL The resin used in this work is poly (ethylene oxide) resin (M W 4,000,000). Thin films of CdS/PEO thin film were prepared by dissolving PEO resin in deionised water at 100 0 C; the CdS powder was dissolved in this solution at the same temperature. This solution mixed together for one hour by using a magnetic stirrer until a homogenous solution is obtained. Then the mixture was cast on a leveled glass substrate and evaporating the solvent at room temperature under normal atmospheric pressure. Samples of different concentrations were dried at room temperature for two days. The drying process was repeated until prepared membranes have fixed weight to ensure the removal of solvent traces and to ensure uniform thickness. Then after completing evaporation, the film was detached from ring surface. In this way, the films were prepared by solution evaporation technique (casting method). (PEO + CdS) were prepared in the laboratory by weight percent method with an accuracy of 0.0001 g., Electronic single pan balance. The prepared films contain 5, 10, 15 and 20 wt%.
