Multilayered CdTe/PSS films were prepared by the electrostatic self-assembly method in an aqueous medium.
Positively-charged cadmium telluride (CdTe) nanoparticles and anionic polyelectrolyte, poly (sodium 4-styrenesulfonate) (PSS) were assembled alternately in order to build up a multilayered film structure. A linear proportion ofabsorbance to the number of bilayers suggests that an equal amount of CdTe was adsorbed after each dipping cycle,which resulted in the buildup of a homogenous film. The binding energies of elements (Cd and Te) in multilayeredCdTe/PSS film shifted from those of the CdTe nanoparticles in the pure state. This result indicates that the interfacialelectron densities were redistributed by the strong electrostatic interaction between the oppositely-charged CdTe andPSS. Electrochemical properties of the multilayered CdTe/PSS films were studied in detail by cyclic voltammetry (CV).
