Abstract This work investigates the preparation of cadmium sulfide nanoparticles (CdS) embedded in the polymeric polyvinylchloride (PVC) matrix. PVC/CdS nanocomposite films were prepared via sol–gel method with deposition by spin-coating on glass substrates. Effects of CdS nanoparticles on the structural, morphological, optical and photocatalytic properties of the synthetized nanocomposite were studied. Results of XRD and Raman analysis confirm the formation of CdS nanoparticles with hexagonal phase in the PVC matrix, with average crystallite size between 17 to 69 nm. The UV–vis spectroscopy reveals that the transmission is between 80 and 95% in the visible region, and a direct energy bandgap between 4.07 eV for 3.85 eV. The PL emission spectra indicate the interstitial cadmium defect states. In addition, the surface modifier (PVC) exert great influence not only on the optical performance of the particles themselves but also on the size distribution of the particle in the PVC matrix. The photocatalytic study shows a good potential of PVC/CdS nanocomposites films for MB degradation under UV light irradiation.

1 Introduction In recent past much attention has been devoted to studies regarding composite polmer-inorganic nanoparticles. The interest in these materials rose due to their biological, optical, electronic and magnetic applications. These potential applications are due to their excellent luminescent and electrical properties [1]. Out of these materials cadmium sulfide (CdS) nanocomposites has been focus of interest * N.

because it is good photosensitive material with potential application in photo-conducting cells and devices, that makes it important material for the application of solar cells, photo-detectors and biological labeling [2]. Reports have reflected that the devices that contain polymer type nanocomposites of inorganic–organic material can be easily processed to produce new properties materials that are better than single segment polymers [3]. Polymer like PVC has attainted tremendous attention in many auspects of life, so i
