Abstract

Polymer light-emitting diode with ITO/PHF/Al structure has been fabricated, where PHF is poly (4,4´-diphenylene diphenylvinylene). The original device has turn-on voltage at 18.0 V. A reduction of turn-on voltage of this device is achieved by using the nanocomposites layer consisting of PHF and SiO₂ nanoparticles as an emitting layer in a single structured ITO/nanocomposite/Al polymer light emitting diode. The SiO₂: PHF was prepared by mixing 1.0 ml of PHF with 0.05 ml of SiO₂ colloidal solution. It was found that the spin-coated nanocomposites has reduced the OLED turn-on voltage to 9.0 V.
