Combination effect of polar solvent treatment on ZnO and polyfluorene-based polymer blends for highly efficient blue-based hybrid organic–inorganic polymer light-emitting diodes

Abstract

Highly efficient blue-based hybrid organic–inorganic polymer light-emitting diodes were synthesized by the combination effect of polar solvent treatment on zinc oxide (ZnO) and hole trap using poly(9,9-dioctylfluorene) (F8):poly(9,9-dioctylfluorene-co-N-(4-butylphenyl)-diphenylamine (TFB) blend to balance the charge carrier transport, leading to maximized recombination of charge carriers and enhance the device efficiency.
