摘要

Hybrid heterojunction thin films, based on poly-(3-octylthiophene) (P3OT) polymer and oleic acid (OA)-capped cadmium selenide (CdSe) nanoparticles (NPs) are prepared by a spin-coating method. The structural and morphological properties of the CdSe NPs and of the hybrid thin films are investigated. The results of the dielectric characterization show that conductivity of the hybrid thin films is dependent on frequency and CdSe NP concentration. The Nyquist plots of the impedance characteristics of the layers exhibit circular features irrespective of the NP concentration. The dependence of the dielectric permittivity on frequency and CdSe NP concentration are studied.
