Abstract Self-organization of nano-CdS particles in polystyrene can be observed by encapsulating the particles with n-dodecyl mercaptan owing to a strong electron transfer interaction between the modified CdS nanoparticles and aliphatic carbons in polystyrene. Consequently, ultraviolet/visible absorption edge of the treated nano-CdS/polystyrene composites is further blue-shifted in addition to the shift caused by quantum size effect, and the fluorescence emission peak of the composite becomes red-shifted and narrow.
