Hybrid nanocomposites for organic light-emitting diodes

We report the investigation of the electrical and optical properties of hybrid nanocomposite which could help to prepare the solution processable and tunable OLEDs. The hybrid nanocomposite was used for the preparation of OLEDs, for which the external quantum efficiency was analyzed to optimize their electro-optical properties. The fluorescence and electroluminescence spectra demonstrated that the color quality and color temperature of the OLEDs can be tuned from cool to warm light. Furthermore, the results suggest that the external quantum efficiency of the PFO-based OLEDs may be increased by 46% when introducing ZnO nanoparticles into the polymer matrix. These hybrid nanocomposites are compatible with low-cost printing electronics technology which could provide high-performance OLEDs for novel applications.
