Abstract

The application of TiO2 nanoparticles and graphite oxides (GO) nanoplatelets as electron- and hole-conducting components of such diodes was investigated. The rectifying properties of the films depended on the choice and sequence of components. Results showed that GO formed a rectifying junction with TiO2 and acted as a charge compensating layer for layers of the [Ru(bpy)3]+-containing polymer RuP. The conductance of RuP-containing thin-film devices prepared from GO was substantially higher than those containing polystyrene sulfonate, which formed resistive multilayer devices with RuP.
