Effects of Postannealing on the Characteristics and Reliability of Polyfluorene Organic Light-Emitting Diodes

We studied the effects of postannealing on the performance of polyfluorene organic light-emitting diodes (OLEDs) with a pure poly(9, 9' -dioctylfluorene-co-benzothiadiazole) (F8BT) emissive layer. After annealing at 150 °C-200 °C, the OLED exhibited the lowest voltage and highest luminance. Thi...
