The electronic properties of hybrid Langmuir-Blodgett (LB) films containing CdS quantum particles (QP) of different size arranged in "cascade like" architectures on gold are studied. The energy distribution of photoelectrons ejected from the gold substrate and transmitted through the LB films is reported. The electronic properties were found to depend on the structure and the organization of the layers relative to the gold substrate, and on the interaction between the metal substrate and the film.
