Abstract

The synthesis and characterization of polymer composite system containing quantum-confined CdS nanoparticles entrapped in an Acrylic acid-hydroxypropyl acrylate copolymer (AC-HAC) is reported. The results showed that the CdS nanoparticles had an average particles size of 3.6nm in diameter and the band edge (λ_edge) of the entrapped CdS nanoparticles was 391nm. The colloidal solution exhibited a band-edge emission peak around 420nm due to the surface passivation. In order to observe the stability of the colloidal solution, it was exposed to air at room temperature for certain days. It was found that the colloidal solution remained as a colloidal solution of CdS nanoparticles even after 65 days exposition.
