Formation of polysaccharide foils containing nanodots (ZnS and CdS)

Abstract: In this work, the CdS and ZnS nanoparticles were synthesized by a “green” route using polysaccharides as capping agent. An in situ synthesis of quantum dots (QDs) in an aqueous solution of potato starch produced foils emitting light on excitation with a UV light. The as-prepared biocomposites were characterized using photoluminescence (PL), IR spectrometric techniques, Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). The absolute molecular weights, radii of gyration, Rg, and thermodynamic properties of the obtained foils are given.
