Sensitization of Photoconductivity in Polymeric Compositions with Fe2O3 and CdS Nanoparticles by an Organic Compound with Intramolecular Charge Transfer

The electric conductivity and photoconductivity of films based on polyvinylbutyral and containing Fe₂O₃ and CdS nanoparticles and an organic compound with intramolecular charge transfer as photoconductivity sensitizer in the visible and near infrared regions were investigated. In the absorption region of the sensitizer the activation energy of the photocurrent is somewhat greater than 0.1 eV and is close to the activation energy of the electric conductivity current.
