Improved performance of hybrid polymer light-emitting device by using inorganic nanocomposite and polymer solutions

We report on the fabrication and characterization of hybrid polymer light emitting device (HPLEDs) with high brightness and simplicity in design with Improved robustness than the conventional polymer light-emitting diodes. We demonstrate the incorporation of Au capped inorganic titanium oxide TiO2 nanocomposite in electroluminescent polymer and fabricated HPLED. We achieved enhanced optical properties of the device and the increased performance of the HPLED is attributed from the electronic charge transport properties of Au capped metal oxide particles in the electroluminescence polymer. The interfacial contact area of electroluminescence polyrner and cathode increased by the incorporated nanoparticles in the organic polymer phase thereby improved luminescence properties.
