Single‐layer polymer light‐emitting diodes are fabricated using poly (9,9′‐dioctylfluorene)‐ co ‐ benzothiadiazole (F8BT) as the emissive layer in contact with metal oxide injection layers ITO/ZnO/Cs 2 CO 3 /F8BT/MoO 3 /Au. Luminous efficiencies of up to 23 cd A −1 are achieved for polymer layer thicknesses near 1 μ m.
