CdS/polyelectrolyte nanocomposites were prepared by using thiol-stabilized CdS nanocrystals and poly(diallyldimethylammonium chloride) in aqueous medium. The colloidal solution displayed the typical weak orange emission, which has been attributed to recombination processes at the crystallite surface. When CdS nanocrystals were introduced in a polyelectrolyte matrix, their luminescence was increased...
