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.
制备了ITO/PHF/Al结构的聚合物发光二极管，其中PHF为聚(4,4′-二苯基乙烯)。原始设备的导通电压为18.0 V。在单结构ITO/纳米复合材料/Al聚合物发光二极管中，采用由PHF和SiO2纳米颗粒组成的纳米复合材料层作为发射层，实现了器件导通电压的降低。将1.0 ml PHF与0.05 ml SiO2胶体溶液混合制备SiO2: PHF。结果表明，自旋涂层纳米复合材料使OLED的导通电压降至9.0 V。
