Abstract

This paper presents formation of CdS nanoparticles in gelatin polymer matrix using successive ionic layer adsorption and reaction (SILAR) technique and the effects of thermal annealing and gamma irradiation on the optical properties of CdSpolymer nanocomposites have been investigated. It has been determined that optical transparency of CdS-gelatin nanocomposites decreased with thermal annealing and gamma irradiation. It has been also observed a small red shift in band gap of CdS due to agglomeration of nanoparticles after treatment. SEM images also show the formation of CdS nanoparicles in polymer matrix with average particles size of about 30nm.
