Investigation of the effect of adding gold nanoparticles on the performance of polyvinyl acetate/ cadmium telluride gamma nanosensor: Introduction of a new gamma nanosensor

Recent advances in synthesis of nanoparticles have paved the way for the development of new nanocomposites with new and unique properties. Precise control of the basic structures of nanoparticles, such as size, shape or formulation, enables us to make composites of these nanoparticles that have superior properties. In this study, a nanocomposite containing cadmium telluride quantum dots in a polyvinyl acetate matrix was synthesized and the capabilities of this nanocomposite as a gamma sensor were studied. Gold nanoparticles were then synthesized and characterized. Three- component nanocomposite of gold nanoparticles / cadmium telluride quantum dots in a polyvinyl acetate matrix was prepared and the properties of this nanosensor against gamma radiation were investigated. The results showed that three-component nanocomposite containing gold nanoparticles have better and more sensitive performance than two-component nanocomposite.
