摘要：Composite films of ZnS nanoparticle-polyelectrolyte were fabricated by the layer-by-layer self-assembly technique. The optical properties and structure of the films were characterized by UV-vis absorption spectra and AFM. The films sensitized by tetrasulfonated copper phthalocyanine (CuTsPc) show wide photovoltaic response range. The surface photovoltages corresponding to the ZnS nanoparticle interband transition and CuTsPc Q band transition in the sensitized Mm are approximately three to four times stronger than those in the ZnS nanoparticle-polyelectrolyte film and CuTsPc film, respectively, which is attributed to the electron transition from the excited state of CuTsPc to the conduction band of ZnS nanoparticles.
