Abstract

We report on the investigation of the electrical and optical properties of hybrid active layers for multicolor and white light-emitting organic devices consisting of a conjugated polymer – polyfluorene (PFO) mixed with inorganic nanoparticles. We have analyzed the behavior of absorption, photoluminescence (PL) spectra as well as electroluminescence (EL) of PFO-based hybrid films after introduction of inorganic nanoparticles having acceptor properties (ZnO, Si) to compare their emission efficiency. We have demonstrated the possibility to tune the PL/EL emission color from green to blue by changing the PFO/ZnO nanoparticles concentration ratio with obtaining the white color at intermediate concentration ratios.
