| 中文摘要 | inverted organic light-emitting diodes (ioleds) with a bottom cathode are of great interest for large-size active-matrix displays due to their easy integration with n-type thin film transistors (tfts) based on low-cost and highly-uniform amorphous silicon and oxide. in this work, a solution-processable electron transporting material 2,7-bis(diphenylphosphoryl)-9,9'-spirobi[fluorene] (sppo13) is employed to blend with a solution-processable hole transporting material 4,4',4 ''-tri(9-carbazoyl) triphenylamine (tcta) to be used as a universal bipolar co-host for blue, green and red phosphors, and for the first time, phosphorescent ioleds are fabricated by solution-processing small molecules. high efficiency and reduced efficiency roll-off are achieved in the solution-processed ioleds, which mainly contribute to the high quality of the solution-processed small molecule films as well as the balanced charge injection in the co-host system. importantly, the solution process is advantageous over vacuum evaporation to deposit multi-component small molecule films, and can be expected to reduce manufacturing costs. our results demonstrate a promising approach to fabricate low-cost and high-performance ioleds for n-type tft-based displays. |
